Consider the following graphic: 200 and let f(r) be the black line that denotes Mario's path on the interval (0, 9]. (a) (1 point) On what intervals is the function concave up? (b) (1 point) On what intervals is the function concave down? (c) (1 point) Where is the function not differentiable? (d) (1 point) Where is the global maximum in this interval? Approximately is fine. (e) (1 point) Where are all the local minimums? Approximately is fine
