Temperature The given graph shows the temperature T in °F at Davis, CA, on April 18, 2008, between 6 A.M. and 6

P.M.

a. Estimate the rate of temperature change at the times

i) 7 A.M. ii) 9 A.M. iii) 2 P.M. iv) 4 P.M.

b. At what time does the temperature increase most rapidly? Decrease most rapidly? What is the rate for each of those times?

c. Use the graphical technique of Example 3 to graph the derivative of temperature T versus time t.
