Determining if a set of points represents a function
is { (0, -4) (2, 7) (4, -4) (1, 9) (3, 7)} a function? true or false answer correctly
1 answer
False. The given set of points is not a function because the x-value 2 is associated with both y-values -4 and 7. In a function, each x-value should have only one corresponding y-value.
