Question

Freddy makes the claim that the inverse function of the function ƒ(x), where f(x)=2x2+2fx=2x2+2, is f−1(x)=x−22−−−√f-1x=x-22

His work is shown below.

For ƒ(x) let y=2x2+2y=2x2+2 then the inverse function is
x=2y2+22y2=x−2y2=x−22x=2y2+22y2=x-2y2=x-22
y=x−22−−−√y=x-22 therefore the inverse function of ƒ(x) is f−1(x)=x−22−−−√f-1x=x-22

In order for Freddie's claim to hold true, which of the following assumptions must be made?
