It will be the RANGE of y=x^2. Also need to specify two different inverses. There will be an upper branch and a lower branch. The domain will be the same for either branch.

, domain is all real numbers.

Using g and h as the two possible inverses of f,
and
x must be real numbers greater than or equal to 0.
