Determine whether the relation is a function. { (-7, - 7), (-7, - 8), (-1, 4), (6, 5), (10, - 1) }

It is not a function.

Step-by-step explanation:

We have given the relation.

{ (-7, - 7), (-7, - 8), (-1, 4), (6, 5), (10, - 1) }

We have to find whether It is a function or not.

A function is a relation that assigns each input a single output.

This relation is not a function.

Because one input - 7 has two outputs - 7 and - 8.

It is not a function.
