Answer 1

sets A and B

Explanation:

Answer 2

Sets A and B . choice D

Explanation:

A relation from a set X to a set Y is said to be a function if each individual element of X is related to exactly one element in Y. In other words, given an element x contained in X, there is only one element in Y that x is related to.

Going by this definition, Sets A and B are functions since each element in x is related to exactly one element in y.

On the other hand, Set C is not a function since the element x = 2 has two corresponding y elements, 1 and 4
