Graph of f
1- 2 In (2-), -5 sxs2
g(x), 2<xs5
The derivative of a function fis defined by f '(x) = -
where the graph of g is a
line segment. The graph of the continuous function f' is shown in the figure above. Let f(3) = 4.
a) Find the x-coordinate of each critical point of f and classify each as the location of a relative
minimum, a relative maximum, or neither a minimum nor a maximum. Justify your answer.
b) Determine the absolute maximum value of f on the closed interval -5 sxs 5. Justify your answer.
c) Find the x-coordinates of all points of inflection of the graph of f. Justify your answer.
d) Determine the average rate of change of f' over the interval -3 sxs3. Does the mean value
theorem guarantee a value of c for -3 <c <3 such that f" is equal to this average rate of
change? Justify your answer.
