See explanation below
Explanation:
((-2,5).(-1,1).(3.1).(-1.-2)} = (x, y)
The first numbers are the x values (domain)
the second numbers are the y values (range)
Domain= (-2, -1, 3, -1)
Range = (5, 1, 1, -2)
The relation is not a function because there are two outputs for one of the domain.
The domain (-1) has two outputs (1 and -2)
