Based on the definition of a function and the rule presented to you at left, would this be considered a function?

Answer 1

To determine whether a relation is a function, we can use the definition of a function: a relation is a function if every input (or element from the domain) is associated with exactly one output (or element from the codomain).

If you can provide the specific relation or rule, I can help you analyze it to see if it meets the criteria of a function.
