Question

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

Answer 1

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
