The domain of a function is the complete set of possible values of the independent variable.
The domain is the set of all possible -values which will make the function "", and will output real -values.
In general, we determine the domain by looking for those values of the independent variable (usually ) which we are allowed to use. (We have to avoid on the bottom if we have a fraction, or negative values under the square root sign).
so, in your case does not matter what value you choose for output will be a real -value
then, the domain is:
(all real numbers)
