Is the relation represented in this table a function?

The relation represented in the given table represents a function.

A function is a relation in which no two ordered pairs have the same input (or x-values) and different outputs (y-values).

Each input has its own corresponding output, that is why the given relation is a function. In other words, a function can only take on one output for each input. We cannot plug in a value and get out two values.
