A warm glass of water, initially at 120 degrees Fahrenheit, is placed in a refrigerator at 34 degrees Fahrenheit and its temperature is seen to decrease according to the exponential function T(h) = 86(0.83)^h +34 where h is the number of hours since placed in the refrigerator

(a) Verify that the temperature starts at 120
degrees Fahrenheit by evaluating T(0)

(b) Using your calculator, sketch a graph of T
below for all values of h on the interval
0 (less than or equal to) h (less than or equal to) 24.
Be sure to label your y-axis and y-
intercept.

(c) After how many hours will the temperature be
at 50 degrees Fahrenheit? State your answer
to the nearest hundredth of an hour. Illustrate
your answer on the graph you drew in (b)
