Answer
Domain = $\{x\in \mathbb{R}\ |\ x\neq 0\}$
Range = $\{y\in \mathbb{R}\ |\ y\neq 0\}$
Work Step by Step
The points (x,y) on the graph are such that
x can be any number except 0
(Domain = $\{x\in \mathbb{R}\ |\ x\neq 0\}$,)
y can be any number except 0
(Range = $\{y\in \mathbb{R}\ |\ y\neq 0\} $)
