Question

Which point could be removed in order to make the relation a function?

{(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)}

(8, 3)
(3, –6)
(–1, 8)
(–4, –2)

Answer 1

(3, –6)

Explanation:

A function is a relation where one input is assigned to exactly one output.

This means that no inputs must be repeated in the relation.

(0, 2), (3, 8), (–4, –2), (3, –6), (–1, 8), (8, 3)

The input of '3' repeats in the relation.

By removing (3, -6), we can make the relation given a function.

Hope this helps.
