Answer:

D. f(x) = 2x - 8

Step-by-step explanation:

What you do is you take the x number and but it into the x spot.

f(x) = 2x  Put 5 into the x

2(5) = 10 does not equal 2.

f(x) = x -3 Put 5 into the x

5 - 3 = 2, but if you plug a different x into it, it doesn't work.

D. f(x) = 2x - 8 is your answer.
