Question

Which set of ordered pairs represents a function?

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

Answer 1

To determine if a set of ordered pairs represents a function, we need to check if each x-value (input) corresponds to only one y-value (output). The sets A and C {(9,3), (2,-2), (1,3), (0,-4)} and {(4,-5), (-2,-3), (6,9), (6,0)} represent functions.

Step-by-step explanation:

A function is a relation where each input has a unique output. To determine if a set of ordered pairs represents a function, we need to check if each x-value (input) corresponds to only one y-value (output).

Examining the sets given, we find that option A {(9,3), (2,-2), (1,3), (0,-4)} and option C {(4,-5), (-2,-3), (6,9), (6,0)} satisfy this condition since each x-value has only one corresponding y-value.

Therefore, the sets A and C represent functions.
