False: the graph changes concavity at the point x = 1 in the interval (2, 1); in fact, f (x) > 0 on (2, 1), while f (x) < 0 on (1, 1). B. True: f has a local minimum at x = 2 and a local maximum at x = 1; the graph of f does have a horizontal tangent at (3, 1), but this is an inflection point. C. True: f (x) = 0 at x = 3, 1, while f (x) does not exist at x = 2; in addition, the graph of f has a vertical tangent at x = 1. keywords: True/False critical point, local extreme, 4 2 002 (part 1 of 1) 10 points 4 2 2 In drawing the graph which of the following properties are satisfied? A. B. C. f (x) > 0 on (2, 1), f has exactly 2 local extrema, f has exactly 4 critical points....
