Question

PLLSSS HELP ME!! Which of the following functions accurately represents f??

Answer 1

C. f(x) = x - 9 is the function that accurately represents f

Explanation:

Plug in a value from the table to check which function is correct

1. Plug in x = 3 and check if you get -6.

A. f(3) = -4(3) + 12 = -12 + 12 = 0 -> 0 ≠ -6 so A is not the correct function

B. f(3) = 3(3) + 2 = 9 + 2 = 11 ≠ -6 so B is not the correct function

C. f(3) = 3 - 9 = -6 = -6 so C is the correct function

D. f(3) = -5(3) - 1 = -15 - 1 = -16 ≠ -6 so D is not the correct function
