Answer
R ={ (3,4),(3,5),(3,6),(4,5),(4,6),(5,6)}
R^(-1) ={ (4,3),(5,3),(6,3),(5,4),(6,4),(6,5)}
Work Step by Step
- As A ={ 3,4,5} and B ={ 4,5,6}
-R be the “lessthan” relation.
-That is, for all (x, y) ∈ A× B, xRy ⇔ x < y
-State explicitly which ordered pairs are in R and R^-1
-By Multiplying each element with the each element of other group
so we will get following realtional form as
R ={ (3,4),(3,5),(3,6),(4,5),(4,6),(5,6)}
R^(-1) ={ (4,3),(5,3),(6,3),(5,4),(6,4),(6,5)}
