Question

Use the following equation to solve the following problems f(x) = 2x – 17

1.) f(x) = 5
2.) f(x) = 18
3.) f(x) = - 13
4.) f(x) = - 45
5.) f(x) = - 11

Answer 1

Explanation:

(1)

f(5) = 2(5) - 17

= 10 - 17

= -7

(2)

f(18) = 2(18) - 17

= 36 - 17

= 19

(3)

f(-13) = 2(-13) - 17

= -26 - 17

= -43

(4)

f(-45) = 2(-45) - 17

= -90 - 17

=-107

(5)

f(-11) = 2(-11) - 17

= -22 - 17

= -39
