Exercises 73-88: Identifr where f is increasing and where f
is decreasing. (Hint: Consider the graph y = f(x).)
73. f(x) = 2x - 1 74. f(x) = 4 - x
75. f(x) = x2- 2 76.f(x) =
77. f(x) = 2x - x2
78.f(x) = x2 - 4x
79.f(x) =
81.f(x) = |x + 3| 80.f(x) = |x - 1|
83. f(x) = x3 84.f(x) = 3
85. f(x) =
87. f(x) =
