Which graph shows a set of ordered pairs that represent a function?

on a coordinate plane, solid circles appear at the following points: (negative 2, 3), (negative 1, 2), (1, 1), (2, negative 1), (2, negative 3), (4, negative 5).

A function must associate only one output to each input. So, you must rule out all the ordered pairs that associate two outputs to the same input.

In the first answer we have both and . So, this is not a function because there is ambiguity defining . Should it be or ?

In the second answer we have both and . So, this is not a function because there is ambiguity defining . Should it be or ?

The third answer is a function because all input-output associations are unique: we have

In the fourth answer we have both and . So, this is not a function because there is ambiguity defining . Should it be or ?
