Range of $R : \left\{- 2 , 2 , - 4\right\}$

Explanation:

Given: R = {(3, −2), (1, 2), (−1, −4), (−1, 2)}

The Domain is the valid input (usually $x$).

The Range is the valid output (usually $y$).

The set $R$ is a set of points $\left(x , y\right)$.

The $y$-values are $\left\{- 2 , 2 , - 4\right\}$
