The following graph corresponds to f'(x), the first derivative of f(x). If the graph does not appear, please reload the page. 1000 500 4 2 -500- Enter the number of critical points/numbers of f(x): Enter the number of relative maxima of f(x): Enter the number of relative minima of f(x): -1000 Based on the above graph of the derivative of f(x), determine the number critical points and relative extrema of f(x). You may assume that f'(x) is continuous, f'(x) is defined for all x, and f'(x) = 0 only when x = -4, x = 0, and x = 4.
