Answer:
Domain {-2,0,2}
Range {-2,0,2}
Relation is a Function
Explanation:
We are given a relation:
{ (-2,-2) , (0,0) , (2,2) }
Domain can be defined as the all possible values of x for a relation. It is considered as a set of all first values of the ordered pairs of a given relation.
Domain of the given relation is {-2,0,2}
Range can be defined as all possible value of y which corresponds to the values of x in the domain. It is considered as a set of all second values of the ordered pairs of a given relation.
Range of the given relation is {-2,0,2}
A relation is a function if only there is one value of y for each value of x. If in the set of ordered pair of the relation, the value of x gets repeated, then the relation is not a function.
As no values of x are getting repeated, the relation is a function.
