Multiple Choice
Identify the choice that best completes the statement or answers the question.

Consider the following table of values where t is hours after 12:00 p.m. noon. A person left their home at 12:00 p.m. for a several hour road trip. The person immediately got on the interstate. Let d(t) represent the distance in miles away from the person is from their home and t represent the number of hours since they left.

The speed limit on the entire interstate is 65 miles per hour. According to the mean value theorem, during what interval of time was the person definitely breaking the speed limit?

a.	between 12:00 p.m. and 12:30 p.m.	d.	between 4:12 p.m. and 5:00 p.m.
b.	between 12:30 p.m. and 1:30 p.m.	e.	between 5:00 p.m. and 5:36 p.m.
c.	between 1:30 p.m. and 2:00 p.m.

The piecewise function is shown in the graph and from to has an average rate of change of . Find all values of c between 0 and 5 that satisfy the conclusion of the Mean-Value theorem.

a.
b.
c.
d.	The function is not continuous on the interval and therefore isn’t guaranteed to have a value c that satisfies the conclusion of the Mean-Value theorem.
e.	The function is not differentiable on the interval and therefore isn’t guaranteed to have a value c that satisfies the conclusion of the Mean-Value theorem.
