Answer 1

To determine which options are not functions, we'd need to see the specific options labeled as 1, 2, 3, and 4. Each option would typically represent a set of ordered pairs or a rule.

A relation is considered a function if every input (or x-value) maps to exactly one output (or y-value). If any x-value is associated with more than one y-value, then it is not a function.

Please provide the details of options 1, 2, 3, and 4 so that I can help identify which ones are not functions.
