Best ResponseYou've already chosen the best response.0technically there is one more property needed to be a function, it is called the "everywhere defined" This just says that everything in the domain must have an associated range value. But you will always have this property if you list the entire relation as ordered pairs.

P.S: A relation is always defined by a set of ordered pairs, even when it's not explicitly. Example: the relation > for natural numbers can still be written as (1,0) (2,0) (2,1) (3,0) (3,1) (3,2)....
