The function f is defined for all x. Use the graph of f' to answer the following questions. (a) Over what intervals is f increasing? Decreasing? NOTE: Enter an inequality such as x <7 f is increasing for f is decreasing for 2 y -2 0 2 -2 (b) Does f have local maxima or minima? If so, which, and where? Choose one at x = f'(x) 8
