Review your knowledge of the mean value theorem and use it to solve problems.

What is the mean value theorem?

The mean value theorem connects the average rate of change of a function to its derivative. It says that for any differentiable function ff and an interval [a,b][a,b] (within the domain of ff), there exists a number cc within (a,b)(a,b) such that f(c)f'(c) is equal to the function's average rate of change over [a,b][a,b].
Graphically, the theorem says that for any arc between two endpoints, there's a point at which the tangent to the arc is parallel to the secant through its endpoints.
