Composition of Functions

[giddyup]

Can anyone help me with this question? I'm not sure how to answer it.

Given the composition, f(g(x))=h(x), find an expression for f(x)=?

Thanks!

I thought the same thing, but this is all the information my professor gave me for this question. I do have the next question which relates to the first one.

Question 2:
"Use the expression from question 1 to solve for f(x) if g(x)=2x+1 and h(x)=4x²+4x+7. Note: It is possible to answer question 2 without using the answer from question 1, but that is not what I am asking for."

Does this help?

h(x) = (2x+1)² + 6

It seems to me, regardless of any additional information provided, that the first question (in its current form) is answerable only with an expression in English. :cool:
