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.

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!
