#

y is the function

stray badger Mar 3, 2025, 2:17 AM

#

astral loom y is the function

How do I go about finding it?

astral loom Mar 3, 2025, 2:17 AM

#

by looking at the graph

#

do you think you know what function this could be ?

stray badger Mar 3, 2025, 2:19 AM

#

(X-1)-2 but that was wrong

astral loom Mar 3, 2025, 2:19 AM

#

ok do you know what a linear function looks like ?

stray badger Mar 3, 2025, 2:19 AM

#

No

astral loom Mar 3, 2025, 2:19 AM

#

do you know what linear is ?

stray badger Mar 3, 2025, 2:20 AM

#

Straight?

astral loom Mar 3, 2025, 2:20 AM

#

kinda its just a constant

#

meaning it stays in a line at all times

#

whether that be positve negative or just horizontal etc

#

so we know the graph in question is 100% not a linear one right

stray badger Mar 3, 2025, 2:21 AM

#

Correct

astral loom Mar 3, 2025, 2:21 AM

#

whats the next one after linear ?

#

btw a linear function would look something like this 2x + 3

#

do you know what a quadratic is ?

stray badger Mar 3, 2025, 2:22 AM

#

Yea

astral loom Mar 3, 2025, 2:22 AM

#

could you give me an example of a quadratic

stray badger Mar 3, 2025, 2:24 AM

#

X^2 +4x +3

astral loom Mar 3, 2025, 2:24 AM

#

ok and do you know what makes that a quadratic

stray badger Mar 3, 2025, 2:24 AM

#

4 and 3 can factor

#

Or they all can factor

astral loom Mar 3, 2025, 2:25 AM

#

how would you factor that ?

stray badger Mar 3, 2025, 2:26 AM

#

X-1 and x-3

astral loom Mar 3, 2025, 2:26 AM

#

ok id like you to just throw away that bit of knowledge as it could be leading you in the wrong direction

#

so a quadratic would be ax^2 + bx + c

stray badger Mar 3, 2025, 2:27 AM

#

Yeas

astral loom Mar 3, 2025, 2:27 AM

#

ok so x^2 + 4x + 3 is a quadratic

#

but what specifically makes it a quadratic is that x is raised to the power of 2

stray badger Mar 3, 2025, 2:28 AM

#

Yeas

astral loom Mar 3, 2025, 2:28 AM

#

A quadratic function is defined as a polynomial where the highest degree of any variable is 2

#

ok and do you know what a quadratic looks like on a graph ?

stray badger Mar 3, 2025, 2:29 AM

#

No

astral loom Mar 3, 2025, 2:29 AM

#

ok thats fine do you know what a parabola is ? or have you heard of it

stray badger Mar 3, 2025, 2:30 AM

#

A u

astral loom Mar 3, 2025, 2:30 AM

#

does it have to be a U?

stray badger Mar 3, 2025, 2:30 AM

#

It could be flipped?

astral loom Mar 3, 2025, 2:30 AM

#

yup thats true

#

and does the graph in question look like a quadratic ?

stray badger Mar 3, 2025, 2:31 AM

#

No?

astral loom Mar 3, 2025, 2:31 AM

#

correct again so it wouldnt be a quadratic

#

so we know its not linear, and that it isnt a quadratic

#

what do you think would be the next step ?

stray badger Mar 3, 2025, 2:32 AM

#

So it’s cubic?

astral loom Mar 3, 2025, 2:32 AM

#

what is a cubic ?

stray badger Mar 3, 2025, 2:32 AM

#

X^3

astral loom Mar 3, 2025, 2:32 AM

#

correct

#

and does the graph look like a cubic ?

stray badger Mar 3, 2025, 2:32 AM

#

Yes

#

So if I type in x^3 that’s the answer?

astral loom Mar 3, 2025, 2:33 AM

#

before you try that why do you think it is the answer

stray badger Mar 3, 2025, 2:33 AM

#

I do

astral loom Mar 3, 2025, 2:33 AM

#

ok but a cubic such as x^3 would start at the origin

#

do you know what the origin is ?

stray badger Mar 3, 2025, 2:34 AM

#

No

astral loom Mar 3, 2025, 2:34 AM

#

so the origin of a graph is (0,0) just the middle of the graph

#

everything starts there unless we move it

#

so quadratics linear cubics, absolutes, logarithimic absolutely everything will be there unless told not to be

#

so does the cubic in question seem to be in the middle of the graph ?

stray badger Mar 3, 2025, 2:35 AM

#

No

astral loom Mar 3, 2025, 2:35 AM

#

so we know it isnt just a cubic right

#

its a cubic that has been shifted/moved

stray badger Mar 3, 2025, 2:36 AM

#

Yeah

astral loom Mar 3, 2025, 2:36 AM

#

in which ways has it been moved ?

stray badger Mar 3, 2025, 2:37 AM

#

Shift on x roughly -4

astral loom Mar 3, 2025, 2:38 AM

#

#

has it moved on the y axis ?

stray badger Mar 3, 2025, 2:42 AM

#

Down 1

astral loom Mar 3, 2025, 2:43 AM

#

ok and how about on the x axis

stray badger Mar 3, 2025, 2:44 AM

#

So it’s (x+3)^3-1?

astral loom Mar 3, 2025, 2:45 AM

#

almost

#

the thing is this cubic is inverted

#

you know how parabolas can be U or upside down U's

stray badger Mar 3, 2025, 2:46 AM

#

So - in the beginning?

astral loom Mar 3, 2025, 2:46 AM

#

yup

stray badger Mar 3, 2025, 2:46 AM

#

Thank you

astral loom Mar 3, 2025, 2:46 AM

#

np

#

one more thing

#

#

this will help you for know you only need to know Linear, Quadratic, Cubic, Absolute, Exponential, and Logarithmic

#

the rest you will learn down the line but the ones you'll use the most are the ones i mentioned

stray badger Mar 3, 2025, 2:49 AM

#

It said was wrong idk why

astral loom Mar 3, 2025, 2:49 AM

#

y=−(x+3) ^3 −1

#

it said that was wrong ?

stray badger Mar 3, 2025, 2:50 AM

#

I put negative sign in front

astral loom Mar 3, 2025, 2:50 AM

#

ok this is hw from your math class right ?

stray badger Mar 3, 2025, 2:50 AM

#

Yea

astral loom Mar 3, 2025, 2:50 AM

#

what are you guys doing in class ?

stray badger Mar 3, 2025, 2:51 AM

#

College algebra

astral loom Mar 3, 2025, 2:51 AM

#

yes but like what are the topics you guys are doing atm ?

stray badger Mar 3, 2025, 2:52 AM

#

I don’t even have class cause they threw me in math online. So for the last month I’ve been learning functions, domains and inverse functions as well as transformations

astral loom Mar 3, 2025, 2:54 AM

#

yeah i cant see it being anything else

#

are you sure you didnt accidentally put some spaces or something in there ?

stray badger Mar 3, 2025, 2:55 AM

#

Maybe but I can’t see it anymore

astral loom Mar 3, 2025, 2:58 AM

#

yeah sorry about that i just dont see it being anything but the answer we got

stray badger Mar 3, 2025, 3:00 AM

#

No worries I can retake it. I’m going to bed now so thank you for everything

astral loom Mar 3, 2025, 3:01 AM

#

yup gn

round night Mar 3, 2025, 7:32 AM

#

astral loom y=−(x+3) ^3 −1

You need to account for the vertical/horizontal stretch

round night Mar 3, 2025, 7:38 AM

#

astral loom y=−(x+3) ^3 −1

Plugging in the point (-2,-3) we get
y=-2(x+3) ^3 −1
