Question

Which set of ordered pairs represents a function? (1 point)

A) {(0, 1), (1, 3), (1, 5), (2, 8)}
B) {(0, 0), (1, 2), (2, 6), (2, 8)}
C) {(0, 0), (0, 2), (2, 0), (2, 4)}
D) {(0, 2), (1, 4), (2, 6), (3, 6)}

Answer 1

D because the pairs represent a function

Answer 2

D.




Explanation: a function can be described as something that has only one output for each input. So an X or input can only have ONE output.


Ex. (2,6) (2,8) would NOT be a function because there are two 2’s with two different outputs meaning it’s not a function.
