Find the relative extreme points ofthe function, ifthey exist. Then sketch a graph of the function. f{x) = 3x2 + 2x3 Identify all the relative minimum points. Select the correct choice below and. if necessary, fill in the answer box to complete your choice. '1'.) A. - "he relative minimum pointfs) isfare Simplify your answer. Use integers or fractions for any numbers in the expression. Type an ordered pair. Use a comma to separate answers as needed.) '1'.) B. ' "here are no relative minimum points. Use the derivative f'(x)= (x4)(x+ 1)(x+4) 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 maximumimaxima islare at x = .
