Let and be differentiable functions with the following properties:

I. f(x) < 0 for all x

II. g(5)=2

If and , then

I started by taking the derivative of h(x) and set it equal to h'(x) but I cant seem to get g(x) by itself. Been working on it for hours, and can't seem to get it right. Anyone know how to solve this tricky problem?

Thanks!
