Question

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

Answer 1

Answer:

Choice 4/D; {(-8, 6), (-8, 5), (-9, 4), (-5, 3)}

Step-by-step explanation

Function: A set of ordered pairs that dont have any repeated x-values

When looking at the choices, look for which pairs have a shared x-value. if they share, they are NOT a function.

{(-9, -7), (-8, -7), (8, 2), (9, -5)}

{(6, 0), (-9, 5), (1, -5), (0, 0)}

{(4, 6), (6, 8), (3, 2), (-6, 8)}

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

{(-8, 6), (-8, 5), (-9, 4), (-5, 3)} has one repeating x-value, -8, signifying that the set of ordered pairs is NOT a function.
