#### Answer

Function
Domain = $\left\{0, 2, 3\right\}$
Range = $\left\{1, 4\right\}$

#### Work Step by Step

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 = $\left\{1, 4\right\}$
