Answer 1

The answer is B

a function is a set of ordered pairs such that for each domain element there is only one range element the set of ordered pairs{(-2,-3),(-3,-2),(2,3)(3,2) is the only set that does not pair a domain elemnt with two or more range elements.

Answer 2

the answer is B. {(-2,-3),(-3,-2),(2,3),(3,2)}
because the domain does not contain any repeated values.
