4. Consider the following graph of a function f. a) Mark above the graph with arrows (Ex: . incr decr )the intervals where the function is increasing and decreasing (use abbreviations "incr" and "decr"). Incr or decr: -2 O 2 6 8 10 12 16 -2 -6 Concave up or down: b) Mark below the graph with arrows (Ex: )the intervals where the function may be concave up and concave down. Use abbreviations "up" and "down". Don't mark any interval where the function is linear. c) Estimate the values of the critical numbers. d) Mark on the graph, with a filled in circle, the points where there is relative minimum or maximum. e) Mark on the graph with an "X" where there is an inflection point. This should agree with a previous answer. f) Estimate the absolute minimum and the absolute maximum for the closed interval [-2, 10]. The absolute maximum of f is _ and occurs at x = The absolute minimum of f is and occurs at x =
