For which function does f (14) = 23? A. f(x) = 1/2x - 20

B. f(x) = 3x - 7

C. f(x) = x +9

D. f(x) = 14x + 23

C.

Step-by-step explanation:

To find the answer we need to put 14 into each of the functions. When it says  we are basically replacing every value in the function with 14.

So for the first function we can say.

A. =

This doesn't equal 23 so we can go to the next function and put in 14.

B.

C.

For C we get which is what we are looking for so the function is .
