Math Help - Tricky double integral question

1. Tricky double integral question

I'm having difficulty finding suitable functions for f(x) and g(x) that fit the criteria given.

Also, it says g(y) in the latter part of the question, do you think that is a typo?

2. 1) Are you SURE that's a square?

2) f(x) and g(y) appear to have nothing in common. You can rewrite two ways. I'll do one.

$\int_{2}^{5} g(y) \left(\int_{-2}^{-1} f(x)\;dx\right) dy$
