Does this set of ordered pairs represent a function? {(–2, 3), (–1, 3), (0, 2), (1, 4), (5, 5)} A. The relation is a function. E
Aleks04 [339]

The correct option regarding whether the relation is a function is:

B. The relation is a function. Each input value is paired with one output value.

<h3>When does a relation represent a function?</h3>

A relation represent a function if <u>each value of the input is paired with one value of the output</u>.

In this problem, when the input - output mappings are given by:

{(–2, 3), (–1, 3), (0, 2), (1, 4), (5, 5)}.

Which means that yes, each input value is paired with one output value, hence the relation is a function and option B is correct.

A similar problem, in which we verify if a relation is a function, is given at brainly.com/question/12463448
