Remember the steps:
1) Verify that the function is continuous on the closed interval and differentiable on the open interval. If not, stop here. You wish you were so lucky :)
2) Find the derivative
3) Set the derivative equal to 0
4) Solve for x (in this case it is c)
5) Use only the values of x that lie WITHIN the interval (don't include end points here)
Complete the odd problems for homework. Solutions are in the online book.
