Which set of ordered pairs does not represent a function? o{-9,8), (6,-4),(-5, -4),(-2,1)}
O {(7,7), (8,-6), (-7,4), (-7.9)}
O{3, -5), (2-5),(-5, 6), (
19) 0
{(2,4), (7.-7), (3,3), (-5,3)}

Below.

Step-by-step explanation:

The second set because we see that the value -7 maps to 4 and to 9. This is a one-to-many relation which is not a function.

Functions are either one-to-one

or many-to-one.
