Question

In Exercises 13-20, find the value of x so that the function has the

given value.
13. f(x) = 6x; f(x) = -24
14. g(x) = -10x; g(x) = 15
15. f(x) = 3x – 5; f(x) = 4
16. h(x) = 14 – 8x; h(x) = -2

Answer 1

Explanation:

13. f(x) = 6x; f(x) = -24

6x = -24

x = -4

14. g(x) = -10x; g(x) = 15

-10x = 15

x = -1.5

15. f(x) = 3x – 5; f(x) = 4

3x-5 =4

3x =9

x = 3

16. h(x) = 14 – 8x; h(x) = -2

14-8x=-2

-8x = -16

x = 2
