The Attempt at a Solution
I assume that I start by finding the integral of f(x). I used wolfram alpha and found that it's apparently the gamma function. I googled the gamma function, but it seems like this crayz thing, and it hasnt gotten me any closer to how to integrate it, especially what f(3), f(4) and f(5) have in common. =/
