[wraith hinge]

A line

[cyan nebula]

Good job

[wraith hinge]

YAY

[cyan nebula]

When u get a like

Line

[wraith hinge]

Yeahhh?

[cyan nebula]

A line has a steepness

That we call

Gradient

[wraith hinge]

Yeah yeah

Okay okay

[cyan nebula]

Good

Can u show the original question

[wraith hinge]

Okay

[cyan nebula]

So to find a graduate

Gradient

[wraith hinge]

Yeah

[cyan nebula]

We have to count squares

[wraith hinge]

OKY okay

Do we ake that triangle thing?

[cyan nebula]

What

What’s ake?

[wraith hinge]

Make

Typo

[cyan nebula]

Yes

So make the triangle

And show me

[wraith hinge]

Okay

[cyan nebula]

Count the squares

[cyan nebula]

And show me

Count the squares

[strange fog]

NO WAY

HE DID IT

[wraith hinge]

HUH?

[strange fog]

YOU GOT THE VALUES

[wraith hinge]

WHAT U MEAN?

[cyan nebula]

Good jov

Job

[strange fog]

nvm keep going perseus

[rough frost]

U got it

[wraith hinge]

Okay okay okayyy

Do I do 2/6?

Or something

And you get like

[cyan nebula]

Ok slow down

[wraith hinge]

Do I simplify it

What the gyatt

Okay nvm

Continue

[cyan nebula]

So to measure gradient

[wraith hinge]

Yeah

[cyan nebula]

We need rise/run

[wraith hinge]

Okay okay

[cyan nebula]

Rise is 2

Run is 6

[wraith hinge]

Yes yes

[cyan nebula]

Do the math

[wraith hinge]

Do I divide 2 by 6?

[cyan nebula]

Yes

Math

What is 2/6

[wraith hinge]

Erm

[cyan nebula]

If ur allowed a calculator use it

[wraith hinge]

0.33

[cyan nebula]

Take 3SF

3 significant figures

[wraith hinge]

Huh

[cyan nebula]

Ok nvm

[wraith hinge]

What is that

[cyan nebula]

Just take 0.333

[wraith hinge]

What

Okay

So 0.333?

[cyan nebula]

Yes

[strange fog]

wait is 3SF the 3 decimal places

[cyan nebula]

No

I’m not explaining that

[strange fog]

what is 3SF

please

now im curious

[wraith hinge]

Yeah what is that

Okay whatever

[cyan nebula]

Not teaching

That

[wraith hinge]

That not important

[cyan nebula]

Off topic

[wraith hinge]

Okay okay

[strange fog]

is it about orunding

the decimal places

thats all i wanna know

[wraith hinge]

So is the gradient 0.333

Evan use Google

[cyan nebula]

Yes

But since

The slope

[wraith hinge]

Yeah

[cyan nebula]

Is going downwards

[wraith hinge]

Yeahh

[strange fog]

no i pulled it out of my ass

[cyan nebula]

Right?

[strange fog]

sorry ill shut up

[cyan nebula]

So the gradient is negative

[wraith hinge]

What?

[wraith hinge]

Ohhhh

So -0.333?

[cyan nebula]

Yes

That’s ur answer

[wraith hinge]

Okayokayyy

Now what is midpoint

[strange fog]

what the

[cyan nebula]

Midpoint

[strange fog]

wait

one second

nothing

[cyan nebula]

Shut up

[wraith hinge]

I agree

😝

[strange fog]

(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

[wraith hinge]

😛

✌🏿

[wraith hinge]

What the fuck

[strange fog]

its fucked

wait

thers no point in teaching midpoint

its just a formula

[wraith hinge]

What u mean?

[strange fog]

just put in the axis

[solid kiln]

faiyrose

[wraith hinge]

Okay so u want me to skip the whole part of midpoint on my exam?

Good job

[cyan nebula]

Brother

[wraith hinge]

What’s that

[strange fog]

oh

thanks

i didint know you can do that

[cyan nebula]

@harsh surge I’m going mad

[strange fog]

TeXit

[wraith hinge]

Huh

[cyan nebula]

Teach them

[strange fog]

so to get the mid point coordinates

[wraith hinge]

I’m tweaking

[strange fog]

pull up the grapgh

with the line

[wraith hinge]

Okay

[strange fog]

its asking you to get the midpoint of

[wraith hinge]

This

[strange fog]

so

on p2

[cyan nebula]

How many years did you retain?

[strange fog]

whats the coordinates

[cyan nebula]

Just curious

[wraith hinge]

Like

4

I think

[strange fog]

0

shes in grade 9

[wraith hinge]

Nuh uh

[strange fog]

she lied about that shit

[wraith hinge]

Boy

[cyan nebula]

oh

[wraith hinge]

What did that say

[cyan nebula]

ic

[wraith hinge]

Okay whatever

Wait so how do I do idpount

Mid

[cyan nebula]

Ok

So

Midpoint

[wraith hinge]

Yeah

[cyan nebula]

Midpoint

Is the middle

Of the line

Easy to understand

?

[wraith hinge]

Yes

[cyan nebula]

Good

Now how would you go about finding that

Any idea?

[wraith hinge]

No

[cyan nebula]

What do u understand from this

Anything?

Do I need to explain this through call 💀

[ocean flame]

what the fuck is this

$(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

[solid kiln]

dinkus

[ocean flame]

so midpoint = p1/2,p2/2

wheres your question

@wraith hinge

[ocean flame]

this?

[wraith hinge]

Nothing

[ocean flame]

alright

so

[wraith hinge]

Yeah

[ocean flame]

tell me the coordinates of p2

with that brain of yours

[wraith hinge]

2,9

[ocean flame]

nice now P1

[cyan nebula]

hav fun

[wraith hinge]

8,7

[ocean flame]

watch me

so now you have the points sandra

[wraith hinge]

Okay okay

[ocean flame]

so out of those two coordinates you have

[wraith hinge]

Yeah

[ocean flame]

sub them into this formula

$(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

[solid kiln]

dinkus

[wraith hinge]

Huh

[cyan nebula]

Watching

[ocean flame]

shit

alright sandra

[cyan nebula]

HAHAHHA

[ocean flame]

you see

so the points are

2,9 and 8,7

lets sub it into this formula

[wraith hinge]

Is it that

Or am I wrong

[ocean flame]

good job

now one sec

$(x_m, y_m) = (\frac{8+2}{2}, \frac7+9}{2})$

SANDRA HOW IS IT GOING

[wraith hinge]

Huh

[ocean flame]

one sec

[cyan nebula]

LMAO

[wraith hinge]

IDK

[rough frost]

DO U UNDERSTAND

[wraith hinge]

I DUNNO

MAKING PROGRESS

[ocean flame]

$(x_m, y_m) = (\frac{8+2}{2}, \frac{7+9}{2})$

[solid kiln]

dinkus

[ocean flame]

there yah go

weve subbed it in

do you have a calculator with you?

[wraith hinge]

Yes

[ocean flame]

do you know how to put this into your calculator

[wraith hinge]

No

[cyan nebula]

[ocean flame]

click brackets

get an open and closed bracket

do you know how to use the fraction button

[ocean flame]

💀

[wraith hinge]

Huh

[ocean flame]

shush im tryna teach her

wait

can you tell me how to make texit solve it

[cyan nebula]

How old r u brother

[ocean flame]

me?

[cyan nebula]

Yea

[wraith hinge]

Is it 5

[ocean flame]

uhh its me the evan guy

one sec

oh good job

faiy tell me

how the bot works

$(x_m, y_m) = (\frac{8+2}{2}, \frac{7+9}{2})$

[wraith hinge]

Huh?

[solid kiln]

dinkus

[ocean flame]

how i solve this

get the bot to

[cyan nebula]

Lmao

[ocean flame]

$(x_m, y_m) = (\frac{8+2}{2}, \frac{7+9}{2})$=

[cyan nebula]

Ya I’m done

[solid kiln]

dinkus

[cyan nebula]

Have fun tho

[wraith hinge]

Erm

[ocean flame]

cya

thank you for trying

[wraith hinge]

8

[ocean flame]

it looks like you taught her rise/run 💀

[cyan nebula]

Yep

[solid kiln]

Result:

3

[ocean flame]

,calc $(x_m, y_m) = (\frac{8+2}{2}, \frac{7+9}{2})$

[solid kiln]

The following error occured while calculating:
Error: Syntax error in part "\frac{8+2}{2}, \frac{7+9}{2})$" (char 16)

[wraith hinge]

What is that

[solid kiln]

Result:

5

[ocean flame]

so we got to segment it

i see

ok

[wraith hinge]

Huh?

[ocean flame]

,calc (7+9)/2

[solid kiln]

Result:

8

[ocean flame]

theres y

so midpoint is 5,9

@wraith hinge

[wraith hinge]

Huh

How did u get that

[ocean flame]

my calculaters far away

i dont want it

mb

5,8

[wraith hinge]

Oh

BEO

[ocean flame]

im half asleep rn

[wraith hinge]

Why?

Samesies

[cyan nebula]

[wraith hinge]

How did u get the 5,8

[solid kiln]

faiyrose

[wraith hinge]

Oh okay okay

[solid kiln]

faiyrose

[wraith hinge]

Ohhh

So is that everything?

[solid kiln]

faiyrose

[wraith hinge]

Then how do I do distance?

Did everybody leave 😔

Oh

What grade u in

[ocean flame]

distance

whats the distance formula

i alr forgot

[wraith hinge]

I dunno

[ocean flame]

AYO

[wraith hinge]

Twinning

[wraith hinge]

Ayo?

[ocean flame]

stfu

dont

stop

[wraith hinge]

Boy what?

[ocean flame]

fai your so mature

you talk in a mature manner

for you age

[wraith hinge]

Who

Huh?

What u mean?

[ocean flame]

im actually done

[wraith hinge]

Wait what?

[ocean flame]

sandra you need to start listening in class

[wraith hinge]

Huh

Bro who r u?

[ocean flame]

whats the distance formula

ITS ME EVACIH

[rough frost]

distance trust guys

[ocean flame]

HOLYSHIT

[wraith hinge]

BEO WHAT

[rough frost]

HELO ME

NO WAY

[cyan nebula]

[ocean flame]

I GOT TIMED OUT FOT ACCIDENTLY SAYING THE N WORD

[wraith hinge]

OH MYGOSH

[rough frost]

EVACHI

[wraith hinge]

WHAT THE FLIP

[rough frost]

TWIN BROTJER

[ocean flame]

SHUT UP

[rough frost]

ITS U

[wraith hinge]

NO WAY

[ocean flame]

ITS NOT THAT DEEP

SHUSH

NOW WHATS THE DISTANCE FORMULA

[rough frost]

Distance formula is the one of the square root

WAIR

[wraith hinge]

BRO I THOUGHT U WERE SOME RANDO

[ocean flame]

:?

[wraith hinge]

I don’t know

[rough frost]

here

[ocean flame]

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}$

[solid kiln]

dinkus

[ocean flame]

there

thats the distance formula

[wraith hinge]

What the hellll

[ocean flame]

so its just subbing in the values

like last time

[wraith hinge]

How do I do that

[ocean flame]

then solving it

wdym

[wraith hinge]

Wait what

[ocean flame]

tell me the coordinates

of the line

in the question

[wraith hinge]

Let me see

[ocean flame]

ill sub it in for you

[wraith hinge]

That was the old one

[ocean flame]

is it the same

[wraith hinge]

Wait ill put it in

Yah

Yeah

[ocean flame]

$d = \sqrt{(8- 2)^2 + (7-9)^2$

What happend

[ocean flame]

$d = \sqrt{(8- 2)^2 + (7-9)^2}$

[solid kiln]

dinkus

[ocean flame]

curly brackey

bracket

anyways

[wraith hinge]

Why does urs and mine look wrong

[ocean flame]

we subbed in the values

[wraith hinge]

Different

[ocean flame]

now we solved it

huh

[wraith hinge]

Yours and mine look different

[ocean flame]

i used the values from the thing you gave me

[wraith hinge]

Did I do it wrong

[solid kiln]

dinkus

[wraith hinge]

Thas my bad

[ocean flame]

wait idk

WAIT

[wraith hinge]

NO I DID ITWRING

[ocean flame]

its asking for x2 first

[wraith hinge]

I REDA IT WRING

[ocean flame]

so switch them around

$d = \sqrt{(2-8)^2 + (9-7)^2}$

[wraith hinge]

Oopy poopy

[ocean flame]

there

[solid kiln]

dinkus

[ocean flame]

now solve

[wraith hinge]

Okay

[ocean flame]

just learn how to use your calculator

and sub in

the exam is not hard

[wraith hinge]

Wait how do I put that in my calculator?

[ocean flame]

square root X? button

then open bracker

2-8

power of 2

plus

[wraith hinge]

Is it 6.324

[ocean flame]

calc, $d = \sqrt{(8- 2)^2 + (7-9)^2}$

[solid kiln]

dinkus

[ocean flame]

what hte sigma

[wraith hinge]

Still here is crazy

[ocean flame]

shush

i hate you

you left

[wraith hinge]

😔

[cyan nebula]

Ya cause it’s impossible

[ocean flame]

ik

[wraith hinge]

NO IT NOT

Filp u then

Is it flipping 6.324

[ocean flame]

here

[wraith hinge]

What the shit

Do I have to do that

[ocean flame]

you got it right

wait

i cropped out

so

is that it?

.close?

do we

[wraith hinge]

NO

IM NOT DONE

[ocean flame]

what

😦

what now

[wraith hinge]

What is that

The linerial

[ocean flame]

fuck

this

can somone

teach her

[wraith hinge]

Please eda

🙏🏽🙏🏽🙏🏽

[ocean flame]

@cyan nebula

please

take my place

i need sleep

[wraith hinge]

Frick u

[ocean flame]

fube

so linear

means like straight

in simple terms

so plot this

[wraith hinge]

Huh

[ocean flame]

uhh

[wraith hinge]

Tf is that

[ocean flame]

one sec

[wraith hinge]

What is starlight

[cyan nebula]

Sorry

Ur not gonna get this in one night

[cyan nebula]

Not this

[ocean flame]

kms

[wraith hinge]

Bro I gotta get this

[ocean flame]

so sandra

linear function

[wraith hinge]

My exam Tommorow

[ocean flame]

is a set of plots

that make a straight line

[wraith hinge]

Yeahh

[ocean flame]

non linear is like a curve

[wraith hinge]

Hat is a starlight line?

[ocean flame]

in your exam use a ruler for linear but sketch the non linear by hand

if you want marks

[wraith hinge]

Wait nvm I read it wrong

[ocean flame]

wdym

[wraith hinge]

Okay okay

[wraith hinge]

I read that as starlight line

Mb guys

[ocean flame]

ok

[wraith hinge]

Okay wait

What this?

[ocean flame]

there

horrible

but just use this

[ocean flame]

uhh

[wraith hinge]

Okay okay

[ocean flame]

im

unn

@cyan nebula

[ocean flame]

for this

[wraith hinge]

Huh

[ocean flame]

r1 r2 r3 r4?

i dont get the question

[wraith hinge]

What’s that

[ocean flame]

im gonna get rest

ask somone else

sorry

i helped you a fair bit

[wraith hinge]

Oh okay

Gn

@cyan nebula

CAN U PLEASE HELP 🥺

[cyan nebula]

[wraith hinge]

Okay then

Let me fail my maths exam

Can somebody help with this

<@&286206848099549185>

[knotty quest]

In probability if it is AND u multiply
If it is OR u add

For R,1

What is probability ull get R out of R and B?

[cyan nebula]

Good luck I spent half an hour explaining gradient

[wraith hinge]

What

I don’t get how to get the r 1 and stuff

[knotty quest]

Did u understand the question?

[wraith hinge]

No

[knotty quest]

Ok so

Basically

[lucid estuary]

is anyone here a mathematican from college or institute

[knotty quest]

There are two things

[royal mirage]

Can somebody help with this, even with the correction i can’t understand

[cyan nebula]

#❓how-to-get-help

[knotty quest]

1st one is he either chooses red or blue

[wraith hinge]

Girl

Oh okay

[knotty quest]

#❓how-to-get-help

[knotty quest]

Second one is he either chooses 1,2,3 or 4

R,1 means

He chose red in 1st case and 1 in second case

Do u know what probability means?

[wraith hinge]

What

[wraith hinge]

Wait I don’t get that

[wraith hinge]

Yes yes I’m pretty sure

[knotty quest]

Ok lemme ask u a simple question

[wraith hinge]

Okay

[knotty quest]

There are 6 numbers

1,2,3,4,5,6

[wraith hinge]

Yeah

[knotty quest]

What is the probability that ull get 4

[wraith hinge]

1/6?

[knotty quest]

Yea

Same thing here

R,1 means

[wraith hinge]

Yeah?

[knotty quest]

1st case he chooses red

And second case he chooses 1

[wraith hinge]

Oh okay

[knotty quest]

So what is the probability that he will choose red?

From red and blue

[wraith hinge]

1/2

?

[knotty quest]

Yes

And to choose 1 from 1,2,3,4?

Brb

[wraith hinge]

1/4?

[wraith hinge]

Okay okay

[knotty quest]

Yess

Is it and or or?

[wraith hinge]

Huh

[knotty quest]

..

[wraith hinge]

And

[knotty quest]

Does the question say

Yes

What do u do?

[wraith hinge]

Multiply it

[knotty quest]

Yes

What will u get

[wraith hinge]

How do I do that?

[knotty quest]

What is the 1st one?

1/2

Second one?

[wraith hinge]

Do I multiply the 1/4 and 1/2?

[knotty quest]

Yes yes

[wraith hinge]

Okay oka

[knotty quest]

That is the probability of R,1

[wraith hinge]

Okay okay

One sec

How do I put that in a calculator

[cyan nebula]

Show pic of calculator

[knotty quest]

Whaaaaaaaaat

[knotty quest]

Do it on ur own smh

[wraith hinge]

It’s that one

[knotty quest]

Y the hell u need a calculator

Which class are u in

[wraith hinge]

Boy cause I don’t get what u mean

[knotty quest]

Wdym u don't get what I mean?

[wraith hinge]

How do I multiply it

[knotty quest]

How do u solve this

1/2 * 2

[wraith hinge]

Erm what

What is that

[cyan nebula]

[knotty quest]

What

U know probability

But u don't know basics of multiplication?

[knotty quest]

I get it lol

[cyan nebula]

Yeaa…

[knotty quest]

@wraith hinge

[wraith hinge]

Huh

I don’t get it

[knotty quest]

What do u not understand?

[wraith hinge]

How to do it

1/2 x 1/4

[knotty quest]

http://m.youtube.com/watch?v=sR83TDp_g2c

[wraith hinge]

How do I do that

HELP ME

NO WAY

BRO

IM SO DUMB

THATS MB

I remember learning that oops

[knotty quest]

Just watch the video ig

[wraith hinge]

So is it 1/8?

[knotty quest]

Yea

Thank god

[wraith hinge]

Oh okay okay

Then what do I do for the rest?

[knotty quest]

Did u understand?

This one

[wraith hinge]

Which one

[knotty quest]

The one I explained u rn

[wraith hinge]

Wait so that?

[knotty quest]

No

[wraith hinge]

What the flip

[knotty quest]

Girl u didn't understand which one I was explaining?

The hel

Hell

[wraith hinge]

What the flip

What u mean

[knotty quest]

I was explaining the

Outcomes one

R,1 thing

[wraith hinge]

Oh what?

[knotty quest]

How the hell u didn't know what I was explaining

[wraith hinge]

I thought u were explaining how to do the first thing

Wait then how do I do the first thing

[knotty quest]

-_-

Same way

[wraith hinge]

Huh

I don’t get it

[knotty quest]

Can't help

[livid inlet]

How can you tell if a function such as this one has an oblique asymptote?

[livid inlet]

but i would like to know in general, when should i search for an oblique asymptote with f(x)/x and f(x)-ax

[trim jolt]

@livid inlet Has your question been resolved?

[ionic pendant]

if you just look at the highest power of x, then that is $\sqrt[3]{x^3} = x$ so we would expect an oblique asymptote

[solid kiln]

cloud

[livid inlet]

so because you have x

that is basically like a cartesian definition

so to + infinity on the x-axis it also goes to + infinity on the y-axis for example?

[ionic pendant]

well no, because it has a negative sign in the actual equation

[livid inlet]

ah yes but in general

if it goes to +infinity and it has something like that x then it could go into + infinity on the y axis which is what y=x looks like

[ionic pendant]

but we would also shoot off to infinity with something like $\sqrt[3]{x^2}$ and that does not have an oblique asymptote, because the function does not behave like $x^1$

[solid kiln]

cloud

[livid inlet]

that would tend to have more like a horizontal asymptote right?

[ionic pendant]

it would look somewhat "horizontal" but it would not have a horizontal asymptote

[livid inlet]

okay

Thank you for your help, cloud, I really appreciate it!

[surreal totem]

Hi everybody,

Is someone available to help me with factorization?

[trim jolt]

@surreal totem Has your question been resolved?

[surreal totem]

Nope

[surreal totem]

no

[cedar anvil]

Do you have a specific question you need help solving?

[barren tartan]

do you still need hel

[trim jolt]

@surreal totem Has your question been resolved?

[surreal totem]

Hey man, thank you for your response. Yes, I need help. I use an iPad where I can share you my screen

Can we connect through zoom, skype or Google meet? also if I can share you my screen here I'd be happy to learn how. It would be great if we discussed the subject lively. (I am not very good at maths)

Please, take a look a this. I tried to make some advances on my own but the problem is that I don't quite understand how the logic of the formulas connect with what I have wrote or with the example.

[torn shale]

F(x)=1+x , r(x)=x^2 , whats the domain of f(r(x))

[torn shale]

So the rule is

Mutual donain between the two functions (^ looking sign that idk the name of) the domain of f(r(x))

[torn shale]

Oh right i forgot

F(x) has domain [-2,3]

r(x)’s domain is [0,2]

ok so

Mutual domain is [0,2] and the domain od f(r(x)) is R (bc its x^2+1)

So the answer must be [0,2] ^ R

Which is [0,2]

But it is incorrect.

Why?

The original question wanted f(r(2)) but appearantly 2 is not a part of tge domain so the answer is undefined)

[torn shale]

But 2 is a part of the domain here

[trim jolt]

@torn shale Has your question been resolved?

[proper kernel]

this is not how domain works

r(x) = x^2's domain is [0, 2]

then find the range of r(x)

the range of r(x) is not R

because the domain of r(x) is not R

the domain of r(x) is only [0, 2]

that limits what numbers you can use to only be from 0 to 2

so that limits what range r(x) can have

figure out the range of r(x) then ping me

[torn shale]

Why do we need the range? @proper kernel the way i was taught used this

Which requires no range

[proper kernel]

well you got it wrong

do you want to try out an answer to see if what Im saying about range works out

[torn shale]

Ok i understand

I understand why range of r(x) is not R

[proper kernel]

before that though, you said you know [0, 2] is incorrect

are you able to check a different answer

you would need to be taught range to do it my way, so theres a disconnect here

[torn shale]

But i dont understand whT it has to do with the question

[proper kernel]

we're not there yet

for now, lets see if the question would even accept using this method as the answer

[torn shale]

Ok do you want me to find the range of r(x)

[proper kernel]

no no

listen

[torn shale]

Kk

[proper kernel]

are you able to check a different answer
you would need to be taught range to do it my way, so theres a disconnect here

[torn shale]

Listening

[torn shale]

Wdym check a different answer

[proper kernel]

you said you know [0, 2] is incorrect

[torn shale]

Yes

[proper kernel]

that means you can check answers

[torn shale]

Yes i have the answer sheet

For tge question

[proper kernel]

what does the answer sheet say then

[torn shale]

The answer is [0,2[ i think

[proper kernel]

its on the shset, theres no need for "I think"

[torn shale]

Ah- theres a little issue

Welll

The question is asking about

F(r(2)) actually

And the answer to that is “undefined”

And this 2 is not a part of the domain

[proper kernel]

hold on there

one step at a time

youre going too fast for yourself

first off, what's r(2)

[torn shale]

And thus [0,2] cant be the answer

[torn shale]

Ok wait

Ah wasnt it x^2

So 4

[proper kernel]

so F(r(2)) is F(4), right

[torn shale]

Yes

[proper kernel]

now is 4 in the domain of F?

[torn shale]

No

[proper kernel]

so what would F(4) be?

[torn shale]

Undefined

[proper kernel]

thats why its undefined

thats all

[torn shale]

Yes

Aha

[proper kernel]

now would you like to know more about this

[torn shale]

What doed this have to do with the question 😭

[torn shale]

Yea

[proper kernel]

??????

bro

the questions asks for F(r(2))

[torn shale]

Listen listen

Im slow

[proper kernel]

slow ≠ confident

[torn shale]

Yes ok i understand

[proper kernel]

I dont see you slowly rereading

I see you asking questions without bothering to try answering them yourself

[torn shale]

I understand why the answer is undefined

[proper kernel]

and thats literally it

[torn shale]

But i dont understand why my solving is incorrect

[proper kernel]

your solving has nothing to do with this

so your solving cant be on the right track

F(r(2)) would be a number or would be "Undefined"

you dont say F(r(2)) is "[0, 2]"

already thats weird to say

you mean something else

[torn shale]

No i just want to use the formal way yk i wanna use the rule

[proper kernel]

I just showed you the formal way

the formal way is "F(r(2)) = F(4) = undefined" and that is the end of the formal way

you mean something else

nothing that you did had anything to do with the original question

[proper kernel]

this does

please understand

[torn shale]

Can you use this to find the domain of f(r(x)) (in interval form)

[proper kernel]

thats a better question

[torn shale]

Yesss but i want the domain

[proper kernel]

to figure that out, we now need to consider that r(x)'s range isnt R

now we have an example of that

you saw F(r(2)) didnt work

[torn shale]

That was my question from the start 😭

[proper kernel]

shouldve said so

[torn shale]

Yes

[proper kernel]

even though 2 is inside [0, 2]

[torn shale]

Aha

[proper kernel]

the real reason you saw was that r(2) = 4 was not in [-2, 3]

so F(r(x)) has a different domain than just F(x) or r(x)

[torn shale]

Yes

[proper kernel]

its smaller than F(x)'s domain

[torn shale]

Bc the 4 is the codomain (range) so it doesnt have to be in the domain.. or does it idk

Wait

No

[proper kernel]

youre close

[torn shale]

4 is not

Codomain

[proper kernel]

youre messing up the words but thats expected

youre close to the idea

4 is in the range of r(x)

[torn shale]

Lemme read what u said

[proper kernel]

but 4 is not in the domain of F(x)

[proper kernel]

on second thought we could just repeat what weve said before so you dont have to bother reading all of it

Ive already repeated the same info too many times so its not convenient

[torn shale]

Im sorry 😭

[proper kernel]

nah dw

[torn shale]

Ok

Aha

[torn shale]

Yes

I get this

And is why we have use the rule 🤩

[proper kernel]

"The" rule?

[torn shale]

This

[proper kernel]

the ^ looking sign is called "intersect"

so $\cap$

[solid kiln]

mtt

[proper kernel]

youre trying to intersect two things

one of them is [-2, 3]

the other one is the range of r(x), knowing the domain is just [0, 2]

[torn shale]

Mhm?

[proper kernel]

so what's the range of r(x), knowing the domain is just [0, 2]

[torn shale]

We get the intersect between domain of f and the range of r

Ah idk how to get the range algebrically

Lemme graph

Zero to infinity?

[proper kernel]

remember the domain is [0, 2]

[torn shale]

Yes

It is

[proper kernel]

whats the biggest number in the domain

[torn shale]

Exactly 2

[proper kernel]

now think that r(x) squares numbers

then look at the domain again

that would mean 2^2 is the biggest number in the range, right

[torn shale]

Omg

Yes

[proper kernel]

yep

0^2 would then be the smallest

[torn shale]

Yes

Ok the range is 0 to 4 wow

[proper kernel]

you didnt need to graph that too

[torn shale]

Im dumb i didnt consider the domain

[proper kernel]

so you can get that the range of r(x) is [0, 4]

[torn shale]

Yes okay

Presume

[proper kernel]

go ask if you need a recap, but I think you have enough to find the domain of F(r(x)) now

[torn shale]

Ok intersect between [-2,3] and [0,4]

[proper kernel]

thats correct

[torn shale]

Holup then

Answer is [0,3]

I hope

What now

[torn shale]

Ok i did it

What now

[proper kernel]

back

yep [0, 3] is the domain of F(r(x))

wait

nvm [0, 3] is not the domain of F(r(x))

[torn shale]

??????

Ok

[proper kernel]

what we got for [0, 3] is the middle step

[torn shale]

Yes

[proper kernel]

now youre looking for the domain

you know [0, 3] is an acceptable range for r(x) and an acceptable domain for F(x)

[torn shale]

Of f(r(x)) yes

[torn shale]

Yes

[proper kernel]

so have [0, 3] be the range of r(x)

then work backwards to find out what the domain of r(x) is

already you have [0, 3] to tell you the middle step of F(r(x))

so working backwards will tell you the beginning step of F(r(x)), otherwise known as the domain

this wont make much sense for now since you interrupted earlier, but for now stick with the steps

[torn shale]

I mean- they gave it to us

[proper kernel]

no no

let me repeat

if [0, 3] is the range of r(x),

then 2 cant be in r(x)'s domain anymore

because 2^2 isnt in [0, 3] is it

[torn shale]

Oh

Wtf

Okay

Yes i understand

[proper kernel]

so what would the smaller domain of r(x) have to be

for the range to only be [0, 3]

[torn shale]

Ah

0 to sqrt3

😭

[proper kernel]

yep

so the domain of F(r(x)) is [0, √3]

[torn shale]

Omg ez

[proper kernel]

you can think of it as

F(r([0, √3]))

F([0, 3])

[torn shale]

Question mark?

[proper kernel]

no question mark

the domain of F(r(x)) is [0, √3]

[torn shale]

Wait uhm

Isnt

0 to sqrt of 3 the domain for r(x)

[proper kernel]

yea its the smaller domain that makes it okay to put into F

the larger [0, 2] domain had a 2 which didnt fit

we made the domain of r(x) smaller

so that way the range of r(x) is [0, 3]

[torn shale]

Aha then how is f(r(x)) is also from 0 to sqrt3

[proper kernel]

I am

[torn shale]

Domain

[proper kernel]

in the middle

of that

[torn shale]

Oh i interrupted you

[proper kernel]

[0, √3] is the domain we chose for r(x)

[torn shale]

Yes

[proper kernel]

so lets see what happens after r(x) happens

you can pretend r([0, √3])

= [0, 3]

this is short for "r(a number inside [0, √3]) = a number inside [0, 3]"

[torn shale]

Okaaaay

Sure

[proper kernel]

now we chose [0, 3] because its in the range of r and the domain of F

so we do F([0, 3])

you saw that [0, 3] only uses numbers inside F's domain of [-2, 3]

so that means we dont have any problems like with 4

so that means F([0, 3]) = [1, 4] with no exceptions

[torn shale]

Thats f(r(x)) right

[proper kernel]

I mean what I type

I dont think you do

are you done yet?

Im not

[torn shale]

Tbh- you lost me here

[proper kernel]

youre rereading past stuff again

[torn shale]

Yes

Iam trying to comprehend what u just did

[proper kernel]

if youre doing that, you shouldnt be interrupting from the beginning

do you want the full explanation

[torn shale]

How is r[ 0 to sqrt3] is [0,3]

[torn shale]

I interrupt when you say smth that i dont understand

[proper kernel]

you said you were OK with that earlier

[proper kernel]

the specific question you chose said you didnt want to understand

[proper kernel]

didnt figure it would play into anything

have you changed your mind or should we continue with this

[torn shale]

I understand why [0 to sqrt3] is in [0 to 3]
