    \[\large \text{Let} \quad f(x)=y\] \[\large y=2x-2\]Taking the inverse, we swap the x and y giving us,\[\large x=2y-2\]Solving for y gives us,\[\large y=\frac{x+2}{2} \qquad \rightarrow \qquad y=\frac{x}{2}+1\] Pretty sure it's option number 3, unless I got confused about the order you posted them :o
