relation is function or not using mapping diagram.
Explanation of Solution
Given information:
The given relation is
Concept used:
- The domain is the set of input values and range is the set of output values.
- In a relation, if the each element of set one is related to exactly only one element of set two.Then the relation is a function.
Consider the given relation
Domain is
Range is
Mapping diagram of given relation:
The each element of set one is related to only one element of set two.
