Question

.
Which of the following ordered pair could NOT be included in this set if it is a function?
{ (-4, 2), (3, 6), (4, 3), (x, y) }
(x, y) = (-3, 6)
(x, y) = (1, 2)
(x, y) = (4, -3)
(x, y) = (3, 6)

Answer 1

Step-by-step explanation:

It cannot be (4, -3) as there would be 2 outputs (3 and -3) for the input 4, therefore it becomes a one-to-many relationship and not a function.
