Chapter 8.4, Problem 2QR

I need help with 45.

In Exercises 7-10, evaluate each function at the given values of the independent variable and simplify. 7. f(x) = 5-7x a. f(4) b. f(x + 3) c. f(-x) 8. g(x) = 3x²5x+2 a. g (0) b. g (-2) c. g(x - 1) d. g (-x) 9. g(x) = [√x-4 4-x a. g (13) b. g (0) c. g (-3) 10. f(x) = x² - 1 1 x 12 a. f(-2) b. f(1) c. f(2) if x ≥ 4 if x < 4 if x #1 if x = 1

What is the output of this function when the Input Is 5? 8- -4- 2 -70 -4 -2 2 4 6. 10 -2 -4 9-
