Chapter 8.2, Problem 65A

The graph of f' is below. Use it to determine where the inflection points are and the intervals where f is concave up and concave down. If there are multiple inflection points, separate with a comma. 6 5 4 3 2 1 f'(x) +x -6-5-4-3 -2 -1 1 2 3 4 5 6 -1 -2 -3 -4 -5 -6+ Inflection point(s) at x = Concave up: Concave down:

The graph of f' is below. Use it to determine where the local minima and maxima for f are. If there are multiple answers, separate with commas. f'(x) 4- -5-4-3-8-1 3 2 1 x 1 2 3 4 5 -1 -2 -3 -4 Local minima at a Local maxima at =
