Moment Generating Function

What is the moment generating function of the probability density function f(x) = 4x-x^2 for 0<x<2? I know it has something to do with E(e^tx) in other words integrate over 2 to 0 e^tx (4x - x^2) dx, but I don't know how to do it.

How do I use this to find the mean and variance of this distribution? (somebody mentioned Taylor decomposition but I don't know what that is)
