Question

Consider the following relation: {(1,12), (3,8), (3, 11), (6,9), (7,11)). Which ordered

pair could be removed so that the relation is a function?

Answer 1

(3,11) or (7,11)

Explanation:

A function cannot have the same second number repeated ( forgot the term for the second number) so removing either (3,11) or (7,11) would leave it being a function
