Answer is (D)... so your method is incorrect. I used your method at first and it was wrong. @vheah

I don't understand how it would be 4/3 if the meaning of f(2) means what would the function equal two if x is two. Where did you get the answer from?

what would the function equal t if x=2 * my bad.

I figured out how to do it. Step 1. Plug 2 into the equation. You get |5-3(2)| = |-1| = 1 Step 2. This expression is now equivalent to 1. Solve for x. 1 = 5 - 3x -4 = -3x 4/3 = x @vheah
