 HW Helper P: 2,944 A nice way of representing the domain is R\{0} which means all the reals except zero. Another way is to state the domain is $$(-\infty,0) \cup (0,\infty)$$ because the open interval excludes the point at zero. If you're working in a system other than the reals, amend accordingly.
