# How do you find the domain of (-2, 1), (-1, 0), (0, -3), (1, -8)?

Apr 19, 2017

Domain: $\left\{- 2 , - 1 , 0 , 1\right\}$

#### Explanation:

The domain is the set of input values and the range is the set of output values.

Input values when given a set of points, are the $x$ values. The output values are the $y$ values.

A point is in the form $\left(x , y\right)$

Therefore, the domain is $\left\{- 2 , - 1 , 0 , 1\right\}$
