The domain are your "limits" on what you can plug in for x.
The basic rules are that you can't take the square root of a negative number, or have 0 as the denominator. Neither of those are applicable, so your domain is all real numbers.

There are no restrictions on x, so the domain is all real numbers, and the range is also all real numbers.
