Hey kinhew93.

I'd say the first thing to do is write down the definition of an odd ad even function. It is asking to show that f(x) = g(x) + h(x) holds for even functions g(x), odd functions h(x) and even/odd functions f(x).

Hint: Try using the fact that f(x)/g(x) = 0 is an even/odd function as a first step.
