Question

Determine whether the relation is a function.
{(-4, 1), (0, 0), (4, 0), (0, 4)}

Answer 1

It isn’t because the x’s is matching

Answer 2

It isn't

Explanation:

An x can't have to y's

way to remember: x=exes y=wives

you can have multiple exes (x's) but only one wife (y's)

0 has two y's
