Question

Which set of ordered pairs does not represent a function?

A). {(4, 4), (-3, -8), (7, -6), (-5, -3)}
B). {(-6, 6), (8, 2), (8, -1), (3, 3)}
C). {(-4, -6), (-9, -7), (6, 7), (0, -6)}
D). {(9, -5), (-5, -5), (0, -9), (8, -3)}

Answer 1

B

Explanation:

The sets have to have different x values to be a function, as we can see in B…

(8, 2) and (8, -1) have the same x values.
