Question

I really need a correct answer please.
suppose f(x)=x^2+2 so find the graph of f(2/3x).
I will attach 4 graphs to choose a correct answer from, thank you.

Answer 1

Are you sure that's supposed to be f(2/3x)? I don't think it makes sense to have an "x" in the argument...

Answer 2

Yes, I promise.

Answer 3

no I think I know what he means

Answer 4

maybe f(2/3)?

Answer 5

It confuses me soo much

Answer 6

is it (2/3)x or 2/(3x) ?

Answer 7

sceenshot

Answer 8

Answer 9

Okay good:
f(x)=x^2+2
f((2/3)x)=(2/3)^2x^2+2

Answer 10

So graph this:
y = 4x^2/9 + 2

Answer 11

Ok hang on

Answer 12

that looks like the first graph. Is that correct?

Answer 13

because 1 and 2 are alike, just ones wider than the other

Answer 14

I don't really know I don't have a calculator, you can check by plotting x=0 and seeing what y is to get a more exact idea..

Answer 15

thank you :3 graph one was correct :)

Answer 16

Okay np =)

Answer 17

Plot 1.jpg is the answer.
