Use the graph of y = f(x) in Problem 2 to identify at which of the indicated points the derivative f'(x)
(a) changes from positive to negative,
(b) changes from negative to positive, and
(c) does not change sign.
Problem 2
In Problem use the indicated points on the graph of y = f(x) to identify points at which f(x) has (a) a relative maximum, (b) a relative minimum, and (c) a horizontal point of inflection.
