Examples
f=((5,2),(3,4),(4,6))f=((5,2),(3,4),(4,6))
Step 1
Since there is one value of yy for every value of xx in (5,2),(3,4),(4,6)(5,2),(3,4),(4,6), this relation is a function.
The relation is a function.
Step 2
Use the definition of the inverse of a function to find the inverse of the set. The inverse is found by swapping the values of xx and yy in each ordered pair.
(2,5),(4,3),(6,4)(2,5),(4,3),(6,4)
