Answer
The domain of the function is the set of all real numbers..
Work Step by Step
When the question asks for the domain of the function, it is asking for what values of x can be legally substituted into the function. (For instance, in the function $\frac{2}{x}$, x $\ne$ 0, for this would make the denominator of the fraction equal to 0.)
In the given function, any real number can be substituted for the variable $x$.
Thus, the domain of the function is the set of all real numbers.
