Question

Which set of ordered pairs does not represent a function?

O{(-3, -3), (6, -1), (4, -4), (9, -3)}
O{(-5,8), (4,3), (-4, -4), (2,8)}
O {(6, -1), (-2, -1), (-8, -4), (5,9)}
O {(4, -2), (1,9),(-1,2), (1,4)}

Answer 1

Explanation:

The first set of ordered pairs is not a function.

The X value of 7 repeats, which means that it is not a function.
