(3, 3) (-7, -1) (5, -1) Graph of 8' The function g is defined and differentiable on the closed interval [-7, 5] and satisfies g(0) = 5. The graph of y = g'(x), the derivative of g, consists of a semicircle and three line segments, as shown in the figure above. (a) Find g(3) and g(-2). (b) Find the x-coordinate of each point of inflection of the graph of y = g(x) on the interval -7
