Question

which set of ordered pairs does not represent a function? answer {(7,1),(-1,7),(8, - 2),(4,1)} {(8, - 8),(8,1),(-1,2),(3,4)} {(-2, - 8),(-8,8),(-8,3),(3, - 8)} {(-2,6),(8, - 8),(-1, - 8),(8,8)}

Explanation:

Step1: Recall function definition

A set of ordered - pairs represents a function if for every x - value there is exactly one y - value.

Step2: Check each option

For option A: The x - values 7, - 1, 8, 4 each have a unique y - value.
For option B: The x - value 8 has three different y - values (-8, 1, 4). So, this set of ordered pairs does not represent a function.
For option C: The x - values - 2, - 8, 8 each have a unique y - value.
For option D: The x - values - 2, 8, - 1 each have a unique y - value.

Answer:

B. {(8, - 8), (8, 1), (-1, 2), (8, 4)}
