Answer:
Step-by-step explanation:
Marriage is one good example of relation and function on condition that its a faithful relationship. One input maps to one output. That's a one to one function. Also a polygamous relation is a function if it's a many to one. Many wives to one man. It's not a function if it's a 1 wife to many men.
So I have given two examples. The other example I will look at is religion, many people to one God. Very good example of a function hahahahaha.
4th example of a relation that is a function is nationality, a person can only belong to one nation even though he/She can be a resident in another nation. So citizenship can be classified as a function.
The last one is mother daughter relation. A daughter is a function of the mother because a single daughter can only have a single mom. But mother is not a function of a daughter because the mom can have many daughters hahahahahaha confusing isn't it. But that's it anywhere.
