Homework Equations


The Fundamental Theorem of Calculus, i.e., taking the derivative of an integral yields the original function.

The Attempt at a Solution


I am not sure how to go about integrating this function because I have never had an integral that has both a variable and a function being multiplied together.

Try a u-substitution. u=x^2 should work.

Wow, I cant believe I didnt try u-sub first!

My final answer came to be
[tex] \frac{f(b^{2})-f(a^{2})}{2} [/tex]

Thanks!
