For each set of sign charts in Exercises 53–62, sketch a possible graph of f.

Restate Rolle’s Theorem so that its conclusion has to do with tangent lines.
Use a sign chart for to determine the intervals on which each function is increasing or decreasing. Then verify your algebraic answers with graphs from a calculator or graphing utility.
It took Alina half an hour to drive to the grocery store that is 20 miles from her house.
(a) Use the Mean Value Theorem to show that, at some point during her trip, Alina must have been traveling exactly 40 miles per hour.
(b) Why does what you have shown in part (a) make sense in real-world terms?
Determine whether or not each function f in Exercises 53–60 satisfies the hypotheses of the Mean Value Theorem on the given interval [a, b]. For those that do, use derivatives and algebra to find the exact values of all c ∈ (a, b) that satisfy the conclusion of the Mean Value Theorem.
