Problems 43-64, summarize the pertinent information obtained by applying the graphing strategy and sketch the graph of y=f(x).
44. f(x) = (x - 3)(x2 - 6x - 3)
46. f(x)=(1 - x)(x2+x+4)
48. f(x) = ().25x4 - 2x3
50.f(x) = -4x(x + 2)
52.f(x) = (x2+3)(x2-1-)
54. f(x)= (x2 - l)(x2- 5)
56. f(x) = 3x5 - 5x4
58. f(x)=2- 3e-2x
60. f(x) = 2e0.5x + e-0.5x
62. f(x)=5 -3 In x
64. f(x)=1 - ln(x- 3)
