Question

Which set of ordered pairs does not represent a function?

O {(-7, -8), (-7,5), (-6,0),(-1,8)}

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

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

{(9,7), (2,7), (-8, -3), (-1,1)}

Answer 1

Answer:(-7, -8), (-7,5), (-6,0),(-1,8)

Explanation:

Functions are relations with one output (y) for any unique input (x).

The first set has two values of y when x = -7: -8 and 5.

The other sets have unique values for each x.
