question (d) and (e)

6. Letf be a function defined on the closed interval -3 5x 5 4 with f(0) =3 and f(-1) = 2. The graph of f', the derivative of of a line segment and a semi-circle, as shown to the right. on a. On what interval(s), if any, is f decreasing. (50 point) ( E3, - 2] , if is decreasing, because y-value is negative at that part of graph of f graph of f' b. For what x-value does f have a relative minimum. Justify your answer. (60 points) at the point x = -2 , f have a relative minimum. " It changes from negative to positive / at 7 = -2 on the graph of fl, also it approched -axis at x = - 2 . c. On what interval(s), if any, is f concave upward. Justify your answer. (50 points) At 4 - 3 , 0) and (2 , 4 ) f is concave upward. " The slope of the graph of f' is positive, and it's increasing at those poin OK. d. Find the x-coordinate of each point of inflection of the graph of f on the open interval -3
