Is (-2,4), (1,3), (5,2), (1,4) a function?

OpenStudy (mertsj):

A function is a relation in which no two ordered pairs have the same first number. So is it a function or not?

OpenStudy (atlchic):

no

OpenStudy (mertsj):

Good for you. There are two ordered pairs that have 1 as their first number so it cannot be a function.
