Answer:
relation
Step-by-step explanation:
First of all, all functions are relations, but not all relations are functions.
A function is a relation where one element in the domain is paired exactly with one element of the range.
A relation assigns one element of the domain to one or more elements of the range.
The range is any set of ordered pairs, while the function is a set where the group of pairs do not share the same first coordinate.
