#### Answer

The domain of the given 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.)
The domain of the given function is the set of all real numbers because we can substitute any real number for $x$.
Thus, the domain of the given function is the set of all real numbers.
