A potato is placed in an oven, and the potatoAc€?cs temperature F (in degrees Fahrenheit) at various points in time is taken and recorded in the following table. Time t is measured in minutes.

a. Suppose it is given that F(64) = 330.28 and F0 (64) = 1.341. What are the units on these two quantities? What do you expect the temperature of the potato to be when t = 65? when t = 66? Why?
b. Write a couple of careful sentences that describe the behavior of the temperature of the potato on the time interval [0, 90], as well as the behavior of the instantaneous rate of change of the temperature of the potato on the same time interval.
