    Look again at reply #12.
    Does that h(x) work?
    If so, why does it work? How does it work?

    Well when I input that h(x) into g(h(x)), the answer is equal to the given f(x), so it does work. I'm not sure how you got that h(x) though.

    I looked at it. I saw what was needed.
    That's how I got it. It really is that simple.

    Re: Combinations of Functions

    Okay I think I've got it now. So I just need to look at the given values and decide what value of h(x) will give me f(x) when combined with g(x)? Thank you very much, you've been a huge help!
