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.
