Use the derivative f'(x) = (x 4)(x + 1)(x + 5) to determine the local maxima and minima off and the intervals of increase and decrease. Sketch a possible graph off (f is not unique). The local maximum/maxima is/are at x = |:|. (Use a comma to separate answers as needed.) The local minimumlminima is/are at x = :I. (Use a comma to separate answers as needed.) The interval(s) of increase is(are) |:|. (Type your answer in interval notation. Use a comma to separate answers as needed.) The interval(s) of decrease is(are) |:|. (Type your answer in interval notation. Use a comma to separate answers as needed.) Which is a possible graph of f
