Function Domain = $\left\{0, 2, 3\right\}$ Range = $\left\{1, 4\right\}$
Every first coordinate is paired with only one second coordinate, therefore the relation is a function. The domain is the set that contains the first components so: Domain = $\left\{0, 2, 3\right\}$ The range is the set that contains all the second components so: Range = $\left\{1, 4\right\}$
