Find the domain and range of the relation (-3,3), (-3,2), (-3,1) (-3,0). Then determine whether the relation is a function

The domain is the x value: (-3)

The range are the y values: (0, 1, 2, 3) in order from least to greatest

No this is not a function because that value of x is "reused". You can "reuse" a y value with different x values but you can't reuse an x value ever, even if the y's are different. x's cannot be the same
