Answer
Domain: $\color{blue}{(-\infty, 0) \cup (0, +\infty)}$
Work Step by Step
Look for the number/s that will make the denominator equal to zero by equating the denominator to zero and then solving the equation.
$x=0$
Thus, the value of $x$ can be any real except $0$
.
In interval notation,
Domain: $\color{blue}{(-\infty, 0) \cup (0, +\infty)}$
