Explanation:

Step1: Recall function definition

A relation is a function if every input ($x$-value) has exactly one output ($y$-value).

Step2: Check $x$-values in the table

The $x$-values are 16, -8, 11. Each $x$-value appears only once, so each has exactly one corresponding $y$-value.

Answer:

yes
