\[y=\frac{x+2}{2}\] The next step is to interchange x and y. Do you want me to take you thru it?

When we interchange x and y we get \[x=\frac{y+2}{2}\] Now we need to solve for y by multiplying both sides by 2 giving\[2x=y+2\] Now you can subtract 2 from both sides to find y which is \[f ^{1}(x)\]

so then, it would be 2x  2 = y, right?

@DeadShot Good work. Youare correct. You can factorise 2x  2 = 2(x  1)

f(x) = (x+2)/2 =>y=(x+2)/2 2y= x+2 x=2y2 x=2(y1) find f^1(x) f^1(x) = 2(x1)
