Question

Determine whether each relation is a function. Assume that the coordinate pair (x,y) represents the independent variable x and the dependent variable y.

{(0,-3),(0,3),(-3,0),(3,0)}

Please help me

If any x value repeats, the relation is not a function

Answer 2

exactly so (0,3) and (0,-3) are not considered a funtional pair

Answer 3

Thank you so much
