# Chapter 7 - Functions and Graphs - 7.2 Domain and Range - 7.2 Exercise Set - Page 460: 73

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 = $\{y\in \mathbb{R}\ |\ y\neq 0\}$)
