The mapping diagram above represents a function since each element in set A is mapped to exactly one element in set B.
How to determine whether or not the mapping represents a function.
From the question, we have the following parameters that can be used in our computation:
Set A and set B
To determine whether or not the mapping represents a function, we need to check whether each element in the domain (set A) is mapped to exactly one element in the range (set B).
In the given mapping, each element in set A is mapped to exactly one element in set B.
So, the mapping represents a function.
