The function f isdifferentiable on the closed interval [-6,5] and satisfies f(-2)=7. The graph of f’ consists of a senicircle and three line segments, as shown in the figure. a)Find the values of f(-6) and f(5). b)Find the absolute minimum value of f on the closed interval. Justify your answer. d)For each of f’’(-5) and f’’(3), find the value or explain why it does not exist.
