Apologies for the confusion in my previous response. The correct answer is:

A. {(0,4)(2,7)(0,4)(1,9)(3,7)}

This set represents a function because each input (x-value) in the set corresponds to exactly one unique output (y-value). In other words, each x-value is associated with only one y-value, making it a function.

In contrast, in set B, each x-value is associated with multiple y-values, which means it does not represent a function.
