Relations Expressed as GraphingWrite each of the following as a relation, state the domainfunction.5.6.2T14 -2- 2 ORelation:MRelatiDomain:DomaRange:RangeFunction:Funct

Answer 1

Relation: {(-2, -2), (-1, 1), (1, 0), (1, 1), (3, -2), (3, 3)}

Domain: {-2, -1, 1, 3}

Range: {-2, 1, 0, 1, -2, 3}

It is not a function

Step-by-step explanation

5. To write this as a relation, we will write this as an ordered pair of values.

That means that we will write out all the x and y cordinates of the relation in the form (x, y).

Relation: {(-2, -2), (-1, 1), (1, 0), (1, 1), (3, -2), (3, 3)}

The domain of a relation is the set of all the input or x values of the relation.

So, the domain is:

Domain: {-2, -1, 1, 3}

The range of a relation is the set of all the output or y values of the relation.

So, the range is:

Range: {-2, 1, 0, 1, -2, 3}

A relation is said to be a function if each x value maps into only one y value.

From the relation given, we have that at least 2 x values map into multiple values.

So it is not a function.
