45-58 (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. You may want to check your work with a graphing calculator or computer. 45. f(x) = x3 - 3x2+ 4 46. f(x) = 36x + 3x2 - 2x3 47. f(x) = 5x4 - 4x2 + 3 48. g(x) = 200 + 8x3 + x4 49. g(t) = 314 - 8+3 + 12 50. h(x) = 5x3 - 3x5 51. f(z) = 27 - 112z2 52. f (x) = (x2 - 4)3 53.
