Part one was the Cauchy's Bound. Now it's the Intermediate Value Theorem. Here are the guidelines:

Write a program for a TI-84 or TI-89 graphing calculator called IVT. Your program should ask for a function, a lower bound, and an upper bound. Then, it should tell you if the Intermediate Value Theorem applies under these conditions and, if it does, the program should locate a zero of the function that lies between the two bounds.

Thanks in advance.
