25-36 (a) Find the intervals of increase or decrease. (b) Find the local maximum and minimum values. (c) Find the intervals of concavity and the inflection points. (d) Use the information from parts (a)-(c) to sketch the graph. Check your work with a graphing device if you have one. 25. f (x) = 2x3 - 3x2 - 12x 26. f(x) = 2+ 3x - x3 27. f(x) = 2+ 2x2 - x4 28. g(x) = 200 + 8x3 + x 29. h(x) = (x + 1)' - 5x - 2 30. h(x) = x - 2x*+ x 31. A(x) = xvx + 3 32. B(x) = 3x2/3 - x 33. C(x) = x1/3(x + 4) 34. f(x) = In(x+ + 27) 35. f(0) = 2 cos0 + cos'0, OS AS 2TT 36. f(1) = 1 + cost, -2 Is 21 whole or in part.
