The following graph corresponds to f'(x), the rst derivative of {(x). If the graph does not appear, please reload the page. J' Based on the above graph of the derivative of for), determine the number critical points and relative extrema of x}. You may assume that f'(x) is continuous, f'(x} is dened for all x, and f'(x) = I) only when X = 4, x = D, and x = 5. Enter the number of critical pointsfnumbers of x): Enter the number of relative maxima of {'{x}: Enter the number of relative minima of for)
