#### Answer

domain: $(-\infty, +\infty)$
range: $(-\infty, +\infty)$

#### Work Step by Step

The domain is the set that contains all the x-values of a function.
The range is the set that contains all the y-values of a function.
The given equation is defined for any real number $x$.
Thus, the domain is the set of all real numbers.
In interval notation, the domain is $(-\infty, +\infty)$.
Since the value of $x$ can be any real number, then substituting any value of $x$ gives a real number.
Thus, the range is the set of all real numbers.
In interval notation, the range is $(-\infty, +\infty)$.
