\fB20. Identify the x-coordinate of any relative extrema of y = x In(x). a) Relative min at x = -1 b) Relative max at x = -1 c) Relative min at x = 1/e d) Relative max at x = 1/e e) No relative extremaEl. The graph of y = f(x) appears on the right. Estimate the points at which the absolute minimum and the absolute maximum occur on the interval [0, 3]. that is, OSx53. a) absolute minimum: (0. 0); absolute maximum: (3, 2) b) absolute minimum: (0, 0); absolute maximum: (2, 4) c) absolute minimum: (-2. -4); absolute maximum: (2, 4) -4 -3 -2 -1 2 3 5 d) absolute minimum: (4, -5); absolute maximum: (-4, 5) e) absolute minimum: (3, 2); absolute maximum: (2, 4) in E2. Find the open interval(s) on which f(x) =x-3x+7 is increasing. a) (-co. -1) or (1, co) (i.e. x 1) b) (1, co) only (i.ex > 1 only) c) (-1, 1) (i.e. -1
