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. Suppose that function f divides x by 3 and adds 11. Write an equation for f(x). 65. Suppose that function f cubes x and adds 20. Write an equation for f'(x). 66. Suppose that function f takes the cube root of x and subtracts 10.
