# What is the domain and range of (5,0),(-7,8),(-7,3),(5,3)?

Aug 2, 2018

Domain: $\left\{- 7 , 5\right\}$

Range: $\left\{0 , 3 , 8\right\}$

#### Explanation:

The domain is also known as the $x$-values and the range is the $y$-values.

Since we know that a coordinate is written in the form $\left(x , y\right)$, all the $x$-values are:
$\left\{5 , - 7 , - 7 , 5\right\}$

However, when we write a domain, we typically put the values from least to greatest and do not repeat numbers. Therefore, the domain is:
$\left\{- 7 , 5\right\}$

All the $y$-values are:
$\left\{0 , 8 , 3 , 3\right\}$

Again put them in least to greatest and do not repeat numbers:
$\left\{0 , 3 , 8\right\}$

Hope this helps!
