What can I study to pass a algebra state test?

[night gate]

so to pass an algebra state test you should study algebra

[cobalt inlet]

WAit fr?

[night gate]

on a serious note tho what does your algebra state test cover ? Is it all of algebra or just algebra 1 or 2 ?

[cobalt inlet]

Algebra 1

[night gate]

Do you know what exactly it covers of Algebra 1

is it cummulative ?

[cobalt inlet]

I don't even know what cummulative means 😭

[night gate]

means covering everytopic that has been shown in algebra 1

not just the most recents

[cobalt inlet]

Ohio state tests aren't shared with us, it's changed every year.

and you need to pass it to graduate

[cobalt inlet]

All topics of algebra 1

[night gate]

alr one second im trying to see if i can find a practice exam thats like the ohio test

[cobalt inlet]

ty

[night gate]

https://vsat1021.cambiumtds.com/student_core/V283/Pages/TestShell.aspx

Thats the algebra 1 state exam practice test

[night gate]

id recomment going through it and just asking questions when you need help

https://oh-ost.portal.cambiumast.com/families.html

click on take a practice test

[cobalt inlet]

thanks

[rose cypress]

Crazy

[cobalt inlet]

😭

[rose cypress]

Just show that it’s not injective and surjective

[cobalt inlet]

huh

[night gate]

bro its algebra one im pretty sure he hasnt learned terms like that

[rose cypress]

Wait sorry, show it’s not surjective yet

Here’s example

[cobalt inlet]

What's this supposed to be

[rose cypress]

[rose cypress]

A diagram of inputs and outputs

[night gate]

ok so do you know what a function is ?

[cobalt inlet]

Something that follows a pattern

[rose cypress]

Uh I guess one case could be like that?

[night gate]

yeah kinda and the notation for it is f(x) g(x) stuff like that

[cobalt inlet]

so the (x) is a number

[rose cypress]

It’s an input

Well yes it’s a number in some cases

[night gate]

so what axkyn was saying with the diagram is that when something is a function it maps onto a unique output

[cobalt inlet]

SIMPLER WORDS GUYS 😭

[rose cypress]

If you input one number and plug into function, the function outputs a new value

[night gate]

You see when i change the value of x the output is always a different number

when i put 1 i get 4

when i put 2 i get 6

[cobalt inlet]

yeah

[night gate]

3 i get 10

thats what a function is remember that for every X there is a unique Y

[cobalt inlet]

how do I make fx a function tho

[rose cypress]

That’s not really a rigorous definition as I notice some flaws but yes for now you can think of it as that

[night gate]

he doesnt need that

[cobalt inlet]

SHE

[night gate]

he can learn a good definition when she takes algebra 2

lol myb

[rose cypress]

Mhm

[rose cypress]

F(x) is typically defined by a certain expression

For instance

[cobalt inlet]

Do u guys use algebra out in the real world 😔

?

[rose cypress]

3x+2

[rose cypress]

Yeah for calculus and boredom

[night gate]

yes i use it when measuring the amount of toilet paper i need to clean my macbooks screen

[rose cypress]

Wait

[night gate]

[rose cypress]

What the fu

[night gate]

why did you take your arrow away

[cobalt inlet]

So how do I make it into a function

[rose cypress]

Cause I don’t do that?

[rose cypress]

Set expression equal to a function

So for instance

F(x)=3x+2

Is a function

You can find out it’s a function by proving it’s a bijection

[cobalt inlet]

[rose cypress]

Oh wait bijection is later on

@night gate help explain pls

[rose cypress]

You just need to define it

[cobalt inlet]

[cobalt inlet]

Definite it how

[rose cypress]

By setting it equal to a function notation I think

So f(x), g(x) etc

[night gate]

forget the arrow that says its a function

[rose cypress]

Why is green one a surjection

[cobalt inlet]

so the letters are the functions

[rose cypress]

Yeah

[night gate]

yes g(x) is a function p(x) is a function anything can be that letter

[cobalt inlet]

Ok

[rose cypress]

Well, f(x) is a function and also could be considered the output

[night gate]

ok and you know that functions have a unique Y output right

[cobalt inlet]

x and y yeah

[rose cypress]

Y=f(x)

X is just input, and the independent variable

It’s just a value you plug in

So x=2

You would denote it as f(2)

So for instance

F(x)=3x+2

[night gate]

for every input i get a different and special output

thats what a function is

[cobalt inlet]

😭 😭

[rose cypress]

X=2 and in this case f(2)=3(2)+2

[cobalt inlet]

[rose cypress]

Apathy

Let’s take a step back

[night gate]

🫡

[rose cypress]

And explain what an input and output is and a whole general definition of a function

Before we provide examples

[cobalt inlet]

My Maths teacher failed me

[night gate]

ok ill leave this to you as i have to go do something i will be back in 40 minutes

[cobalt inlet]

[rose cypress]

What they teach you

[cobalt inlet]

NTHING

LITERALLY NOTHING

[night gate]

just try organic chem tutor he basically taught me everything

[rose cypress]

I don’t do pedagogy

[night gate]

he probably has a video for this exact topic

[rose cypress]

Mhm

[rose cypress]

Oh I got you then

[cobalt inlet]

n she wonders why we all got f's

it's a reflection of your teaching

[night gate]

https://www.youtube.com/watch?v=7JZ0IfCQ488

this is a perfect video

watch that

hes the goat

[rose cypress]

https://www.khanacademy.org/math/algebra/x2f8bb11595b61c86:functions

This is also good

[night gate]

dont watch types of functions as it might confuse you

[rose cypress]

Just watch these videos in chronological video

[night gate]

so from 5 to 11 minutes dont watch that part

just watch the first 5 minutes of that video

[rose cypress]

@cobalt inlet

[night gate]

then ask axkyn any question you have

ill be back in 40

[cobalt inlet]

kk

[rose cypress]

Just self study smh

If teacher incompetent then teach yourself

[cobalt inlet]

This is so sad

I'm gonna have to put hours into learning something I'm never gonna use again

[rose cypress]

What do you like to do

[cobalt inlet]

I guess be lazy

lay down

read

play some video games

[rose cypress]

Hm

Watch the course I sent you

I promise it will refresh your knowledge on this

How’s it going @cobalt inlet

[cobalt inlet]

Uhm

[cobalt inlet]

do I watch all the learn stuff and then go to practice?

[rose cypress]

Yeah

How you doing

[cobalt inlet]

I'm watching the video but I don't understand how he's getting the output

[rose cypress]

Show me an example?

[cobalt inlet]

Like how you get the output to any input

[rose cypress]

It depends on the equation

[cobalt inlet]

For these he's literally just adding +1 to the input

[rose cypress]

+2

Oh the expression is x+1 then

[rose cypress]

The input is this

[cobalt inlet]

and then these you find the output by even and odd?

[cobalt inlet]

Yeah he's adding 1 to 0 and 1 to 2

[rose cypress]

I would watch apathy’s video then

[cobalt inlet]

Maybe I'm js not meant to comprehend Algebra

[rose cypress]

No it’s just you are exposed to extreme material

https://www.youtube.com/watch?v=52tpYl2tTqk

[cobalt inlet]

I think I understand

[rose cypress]

Like you don’t have the knowledge required to do certain things you just need to get that knowledge

[cobalt inlet]

so this would be -1, -1

or

[rose cypress]

Show entire problem again pls

Also for this problem specifically

I think a very important clarification is needed

[rose cypress]

For a function to exist, you must have one input and one pout

Output

[cobalt inlet]

Yeah

[rose cypress]

You cannot have one input going to one output

For instance

A wrong function would be you inputting 2 into the function getting 3 and 4

That’s just not a function

[rose cypress]

However two inputs can reach one output

[cobalt inlet]

if you input 2 into the fuction as x wouldn't the output be 4

[rose cypress]

How’d you get that

[cobalt inlet]

well

x | output say f(x)

-2 | -2

[rose cypress]

How’d you get 4 though

[cobalt inlet]

-2 x (x) = 2

[night gate]

im back

[rose cypress]

Yo

[cobalt inlet]

I meant -2

[cobalt inlet]

Heyy

[tacit karma]

hey what's the question

[tacit karma]

does it specify what kind of function or just function

[cobalt inlet]

That's all it says

[tacit karma]

i see

maybe concentrate on g(x) first

for it to be not a function you need to make either x=-1 or x=6 map to another value

[tacit karma]

that doesnt work

you must have in either -1 twice or 6 twice in the column with x

for g(x)

[tacit karma]

x
-1
-1
6
or
x
-1
6
6

[night gate]

ok now im actually back was busy with something

did you watch the video i sent ?

[cobalt inlet]

No it wasn't making sense

[night gate]

ok thats fine lets work it out then like anti algebraist was saying lets just focus on the function g(x) first

so remember for a function to work the x value has to have a specific y value right ?

[tacit karma]

do the entries on the left table depend on the right table?

@cobalt inlet

[cobalt inlet]

Huh

[tacit karma]

you seemed to have left the channel so i pinged you

[cobalt inlet]

Yeah I did

[tacit karma]

oh

[night gate]

[cobalt inlet]

I've decided to just fail 😔

[rose cypress]

Don’t give up just yet

[night gate]

would you like to hop into a vc so its easier to expalin ?

[rose cypress]

https://tenor.com/view/peepo-swinging-feet-swinging-legs-waiting-kicking-feet-gif-3676656821865359356

[tacit karma]

you need to tell us what it is you are struggling with

all the explanations are for no good if they dont explain what you are questioning

[cobalt inlet]

How to find the missing inputs and outputs

I thought you just multiply to find them

[tacit karma]

here you dont do any operations

you dont know how f(x) and g(x) look like

you just know some numbers that output some other numbers

[tacit karma]

the goal here is to input the right numbers and output the correct numbers so that f(x) is a function but g(x) isnt

since they dont codepend, you can make it easy

first you need to know what makes a function a function

[rose cypress]

Explain the definition of a function

[tacit karma]

so you then know what makes a function not a function

one has not to do with the other rn

@cobalt inlet are you here?

[cobalt inlet]

yes

[tacit karma]

did you understand so far

you need to tell us

[cobalt inlet]

what makes a function

is two sets of things

an input and an output connected together

[tacit karma]

you are taking the right path

the most crucial thing is how a function works

[cobalt inlet]

The input controls the output

[tacit karma]

yes

and

an input has always one output

for example

your keyboard is a function

[cobalt inlet]

is it

[tacit karma]

your input is your pressing a key

the output you expect is the key

you dont expect two keys to pop out

if I type a then a pops

one input gives one output

[cobalt inlet]

Then click -1 and -1 comes out

[tacit karma]

you dont get suddenly when pressing a you a b

[tacit karma]

for example

the most important thing is that it's one output

[cobalt inlet]

The input is the x and the output is the y?

[tacit karma]

yes

[rose cypress]

F(x) can also be considered the output as well

[tacit karma]

the set of letters can be the input
and the output can be again the set of letters

the function just does something with these letters

what it does, is not really important

just know it's a system

another function could be

you input your name and outputs your surname

you wouldnt expect to output two surnames

or a function that tells you your age based on your birthday

you would expect to output two ages at the same times

see how counterintuitive that is, how intuitive functions are

[cobalt inlet]

yup

[tacit karma]

now back to this

say g(x) was age

[rose cypress]

[tacit karma]

ok nah

say g(x) was temperature

yea

[rose cypress]

Lmao

[cobalt inlet]

NO

[rose cypress]

Bro thought -1 lmao

[tacit karma]

x was temperature in the morning and g(x) in the evening

[cobalt inlet]

let's say g(x) is how many days till my birthday

[tacit karma]

now to make g(x) not a function you would just need to make either -1 or 6 output two values

[tacit karma]

ok lmao

[rose cypress]

[tacit karma]

negative days would be your birthday happened

[rose cypress]

Mhm

[cobalt inlet]

kk

[tacit karma]

what would be the input

to make sense of it

like just days

[cobalt inlet]

53

[tacit karma]

uhm what

[cobalt inlet]

That's days

53 days

[tacit karma]

no i mean like how do you make sense of the -1

if you tell g(x) -1 what does it do

[cobalt inlet]

HUH??

[tacit karma]

temperature was much better

[cobalt inlet]

Cap

53 days Anti Algebraist

[tacit karma]

let's say g(x) is how many days till my birthday
(-8 days remain)

thanks

[cobalt inlet]

okay

-8 DAYS OMG IT PASSED 8 DAYS AGO?

[tacit karma]

ok

say x was just some day, and g(x) tells us how many days (from x) till your bday

so -1 would just be yesterday

[rose cypress]

Lmao

[cobalt inlet]

This is so lame

[tacit karma]

now to make g(x) not a function you need to make sure that g(-1) or g(yesterday) gives you two values

thats all

[cobalt inlet]

g(-8)

is what you're saying

[tacit karma]

no

-8 is not even x

g(x) = -8

[cobalt inlet]

yes

But yesterday like you said 8 days ago

INPUT -8 to the (x)

[cobalt inlet]

like showed in this

[tacit karma]

yes but the key is you dont

do that in f(x)

in g(x) you must input -1 again or 6

your only choices

so it doesnt become a function

[tacit karma]

say 6

now you need to assign two values to 6

that are not the same ofc

[cobalt inlet]

Why are u putting a 6 there

[tacit karma]

because you are not listening

[cobalt inlet]

I AM WHAT?

[tacit karma]

you aren't

thats it

either you focus your shit up or iam gone

[cobalt inlet]

Clearly I'm focused cause I've read everything you've said

Im js not understanding

[tacit karma]

reading without comprehension

thats lack of focus
