Answer
$\text{This relation is a function.}$
$\text{Domain: } \{0,1,2,3 \}$
$\text{Range: } \{-2,3,7 \}$
Work Step by Step
A relation is a function if each element in the first set is associated with exactly one element in the second set.
This relation is a function because there are no ordered pairs with the same first element and different second elements.
The domain (set of all first coordinates) of this function is $\{0,1,2,3 \}$
The range (set of all second coordinates) of this function is $\{-2,3,7 \}$
