Question

LAst one, B?

Answer 1

so you have to pick the one that gives you h(x) when you substitute g(x) into f(x)

this is a lot of messy algebra but you'll have to try them one by one

Answer 2

start with a) let the x in f(x) be equal to 4x^2 and calculate f(x)

Answer 3

so (4x-2(x+1))^2?

Answer 4

I mean F(4x-2)=4x-2?

Answer 5

f(x) = (x+1)^2 ==> ([4x^2]+1)^2 and that doesn't get us anywhere close to h(x) so let's keep going

Answer 6

let's try answer c)

Answer 7

okay

Answer 8

f(x) = 4x^2 ==> ([x+1])

Answer 9

Right?

Answer 10

take "x+1" and let that be your new x in f(x) = 4x^2

Answer 11

4(x+1)^2

Answer 12

good, and that's exactly what h(x) is so c is our answer.
