D. 2x-1
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! If the first is substituted, the function is x-6+7=x+1, and f(2)=3.
If the second is substituted, the function is x+13, doesn't work
the third becomes 3x+6, which doesn't work
The fourth becomes 2x+6 which also doesn't work.
