Question

Tell whether the relation is a function. Explain.

Answer 1

It is not a function.

Explanation:

A relation can only be a function if every input (x-value) of the set of values of the relation, has exactly one output (y-value).

In the relation given, one input, -2, has two output related to it, 5 and 0. That's (-2, 5) and (-2, 0).

Therefore, the relation is not a function.
