#### Answer

The domain of the given function is the set of all real numbers except 0.

#### 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.)
Find the number that makes the denominator zero by equating the denominator to zero:
$2x=0
\\x=\frac{0}{2}
\\x=0$
Thus, the denominator is equal to zero when $x=0$.
Therefore, the domain of the given function is the set of all real numbers except 0.
