What is the largest value of x that would make the following list of a points not a function.

Question

{(___,
14
14),

Answer 1

The largest value of x without repeating would be any number less than 14. For example, if x is equal to 13, the list would be as follows:

{(13, 14),
(13, 14)}

Since there are multiple outputs (14) for the same input (13), the list does not represent a function.
