WebbReflexive Relation Definition In relation and functions, a reflexive relation is the one in which every element maps to itself. For example, consider a set A = {1, 2,}.

The previous 6 alternatives are far from being exhaustive; e.g., the red binary relation y= x2is neither irreflexive, nor coreflexive, nor reflexive, since it contains the pair (0, 0), and (2, 4), but not (2, 2), respectively.
