-2 -2 0 3 5 Graph of f Let f be function defined on the closed interval [-5, 5]. The graph of f, consisting of two semicircles and two line segments, is shown above. Let g be the function given by 9 (x ) = f (t ) at . a. Find g(-3), g' (2), and g" (4). b. At what x-values does g have a relative maximum on the interval (-5, 5)? Justify your answer. c. Where is g concave up on the interval (-5, 5)? Justify your
