# What is the domain and range of {(1,4) (0,-2) (2,3) (-1,4) (-3,0)?

Sep 19, 2016

$\text{Domain={-3,-1,0,1,2}, &, Range=} \left\{- 2 , 0 , 3 , 4\right\}$.

#### Explanation:

When a Relation or Function , say, $f$, is defined as a Set of

Ordered Pairs, i.e., $f = \left\{\left(x , y\right)\right\}$., its Domain and Range ,

denoted by $D \mathmr{and} R$ resp., are the Sets , defined by,

$D = \left\{x : \left(x , y\right) \in f\right\} , \mathmr{and} , R = \left\{y : \left(x , y\right) \in f\right\}$.

Clearly, in our case,

D={-3,-1,0,1,2}, &, R={-2,0,3,4}.
