- d_tr 5y agoI am not sure what you mean by "relation" and what the benefit would be. There is a definition for "relation" in mathematics. A function is a type of relation and a relation is a set. But you probably have something else in mind.
- ducttapecrown 5y agoMultivalued functions are types of relations. Relations are more general than multivalued functions because relations don't have to be defined on the entire domain.
- kergonath 5y agoWhat’s wrong with the square root, apart from the fact that it’s not defined over all of R? It’s a fairly well behaved function overall.
