Determine which of the mapping diagrams represent the relationship that is not a function
A mapping diagram represents a relationship between two sets, where each element in the first set is associated with exactly one element in the second set. If there exists any element in the first set that is associated with more than one element in the second set, then the relationship is not a function.
In a mapping diagram, if any element in the first set has multiple arrows pointing to different elements in the second set, then it is not a function.
Without the mapping diagrams provided, I cannot determine which one represents a relationship that is not a function.
