Question

Which sets of ordered pairs represent relations that are functions? You may choose more than one correct answer.

(1,0), (2, 0), (3, 0),(4,0)
(2, 3), (2, 4), (2,5), (2, 6)
(1, 1), (2, 2), (3, 3), (4,4)
(1, 3), (-1, 4), (1, 4), (-1,3)
(6,-6)(-6, 6), (5,-5), (-5,5)

Answer 1

Answers:

(1,0), (2, 0), (3, 0),(4,0)

(1, 1), (2, 2), (3, 3), (4,4)

(6,-6)(-6, 6), (5,-5), (-5,5)

Explanation:

Functions have one input that corresponds to exactly one output. The inputs must NOT repeat.

The second set is not a function:

(2, 3), (2, 4), (2,5), (2, 6)

The fourth set is not a function:

(1, 3), (-1, 4), (1, 4), (-1,3)

All other sets given are a function because they do not repeat inputs.
