- For Exercises 75–84, determine the r- and y-intercepts for the given function. (See Example 7) 75. f(x) = 2x – 4 76. g(x) = 3x – 12 77. h(x) = |x| – 8 78. k(x) = -|x| + 2 79. p(x) = -x + 12 80. q(x) = - 8 81. r(x) = |x – 8| 82. s(x) = |x + 3| 83. f(x) = Vx – 2 84. g(x) = – Vx + 3arrow_forwardFor Exercises 61–66, fill in the blanks and determine an equation for f(x) mentally. 6 from x. 62. If function f multiplies x by 2, then f 61. If function f adds 6 to x, then f Function f is defined by f(x) = x + 6, and function f is defined by fx) = -1 by 2. Function f is defined by f(x) = 2x, and function -1 f is defined by f'(x) = 63. Suppose that function f multiplies x by 7 and subtracts 4. Write an equation for f(x). 64.
