Do you mean: g(x) = x-squared?
Then, yes it is a function (a quadratic acutally).
The domain is all x-vaules. Are there any values of x that would make this function undefined? Since it's x^2, there aren't since any real number squared is still a real number. So the domain would be all real values of x or (-infinity, +infinity).

Yes, it's a function. Since you can square any number and it's still rational, then the domain would be anything from negative (-) infinity >>>> positive (+) infinity

yes it is a function, and the domain is all the reals
