# What is the domain and range of the relation: {(5,-7),(4,4), (3,2), (2,-7)}?

Dec 12, 2016

Domain: $\textcolor{g r e e n}{\left\{5 , 4 , 3 , 2\right\}}$
Range: $\textcolor{g r e e n}{\left\{- 7 , 4 , 2\right\}}$

#### Explanation:

Given a set $\left\{\left(x , y\right)\right\}$
by definition
$\textcolor{w h i t e}{\text{XXX}}$the Domain is the set of values for $x$
and
$\textcolor{w h i t e}{\text{XXX}}$the Range is the set of values for $y$
