Inverse of a Relation

The new relation formed by interchanging the domain and range of a relation R from a non-empty set A to a non-empty set B is called the inverse relation of R, denoted by R-1.

In other words, the set of ordered pairs obtained by interchanging the first and second elements of each ordered pair in R is called the inverse relation of R and is denoted by R-1.

R = { ( a , b ) }
R-1 = { ( b , a ) }

Question 1 of 8
Note: To find R-1, interchange the first and second elements of every ordered pair in R.
