Identify the domain and range of each relation. Use a mapping diagram to determine whether the relation is a function.
To identify: the domain and range of given relation and to find whether the given
relation is function or not using mapping diagram.
Explanation of Solution
Given information:
The given relation is
Calculation:
The domain is the set of input values for which the function has defined output values.
The range is the set of output values for the inputs values which are from domain.
Hence, the domain
Mapping of given relation is shown below
From the above mapping diagram,
Each element of set one is not related to only one element in set two.
Hence, the given relation is not a function.
