How do you so this i do not understand

This is a function.

Step-by-step explanation:

The four given input values, {-6, -2, 1, 3}, are all unique, and each has a corresponding y-value.  So there is no ambiguity regarding the output (function) values.  Therefore, the relation shown represents a function.
