Inverse of a Relation (Jump to: Lecture | Video )


A Relation is a set of ordered pairs.

Figure 1.
Inverse Relation

If Relation A is made up of ordered pairs (a, b), Relation B is its inverse if it possesses all possible ordered pairs in the format (b, a).

Figure 2.

Above are a relation and its inverse.

Figure 3.

If a single point is not the inverse of its mapped point, then the functions are not inverses of each other.
