Question

Which set of ordered pairs does not represent a function?

Answer 1

Answer:

The first answer: {(-3, 9), (7,9), (9, 1), (7, 3)}.

Step-by-step explanation:

If any set of ordered pairs have at least two of the same x values(the first number in the coordinate), it is not a function.

Answer 2

Answer:

$\{(-3,-9),(7,9),(9,1),(7,3)\}$

Step-by-step explanation:

A relation is a function only if each element of the domain is related exclusively to one element of the codomain. Then, the following set of ordered pairs is not a function:

$\{(-3,-9),(7,9),(9,1),(7,3)\}$
