To determine if the relation given is a function, we need to check if each input (left side) has exactly one corresponding output (right side).

In this relation:

The input −19 is associated with three different outputs: 24, −17, and 33.

The input −5 is associated with the output 15.

Explanation:

A. This option is incorrect because −19 has three different outputs (24, −17, 33), violating the definition of a function where each input should have exactly one output.
