To check: The given relation is a function or not.
Answer to Problem 55SR
The givenrelation is a function.
Explanation of Solution
Given information:
The relation is as follows.
Calculation:
A function is a relation in which each element of the domain is paired with exactly one element of the range. In a function, there is exactly one output (element of range) for each input (element of domain).
Here, each member of the domain in the given relation is paired to only one member in the range. So, this mapping is referred to as a function.
The paired elements in this function are
Here, more than one element in the domain is paired to the same element in the range, such as
Even if more than one element in the domain is mapped to the same element in the range, the relation is still considered as a function.
Therefore, the relation is a function.
