Question

12. If f(x) = -9x + 8, then find f(-2). (Lesson 2-1)

A. -84
B. -8
C. 26
D. 200

Answer 1

C. 26

Explanation:

`{ \tt{f(x) = - 9x + 8}}`

- f(-2) implies that x = -2, therefore; we substitute -2 in place of x in the function;

`{ \tt{f( - 2) = - 9( - 2) + 8}} \\ \\ { \tt{f( - 2) = 18 + 8}} \\ \\ { \tt{f( - 2) = 26}}`
