1)     Verify that F(x) is an antiderivative of the integrand f(x) and use Part 2 of the Fundamental Theorem to evaluate the definite integrals.

2)     Use the suggested u to find du and rewrite the integral in terms of u and du.  Then find an antiderivative in terms of u, and, finally, rewrite answer in terms of x.

3)     Use the change of variable technique to find an antiderivative in terms of x.

4)     Evaluate the definite integrals.

5)     Sketch the graph of each function and find the area between the graphs of f and g for x in the given interval.
