Proving that a function is bijective + finding its inverse function.

Hello!

I'm trying to prove that the following function is bijective and find its inverse function.

Let X be a set and A a subset of X.

f : P(X) → P(X)
    A →  the complement of set A

It's the first time I'm asked to do this with power sets and sets, so I have no idea of what I'm supposed to do.

All help is much appreciated!
