Domain: $\color{blue}{(-\infty, 0) \cup (0, +\infty)}$
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: $\color{blue}{(-\infty, 0) \cup (0, +\infty)}$
