Let S = {a,b,c,d,e} and R be a relation on S defined by,
`R={(b,a),(b,d),(d,b),(d,d),(e,b)}` ,
find the inverse of R.

Let S = {a,b,c,d,e} and R be a relation on S defined by, R={(b,a),(b,d),(d,b),(d,d),(e,b)} , find the domain

Let S = {a,b,c,d,e} and R be a relation on S defined by, R={(b,a),(b,d),(d,b),(d,d),(e,b)} , find the range.

If A = {a, b, c, d} then a relation R = {(a, a), (b, b), (c, c), (d, d)} on A is :

If R is a relation on NxxN defined by (a,b) R (c,d) iff a+d=b+c, then

Given a set A = {a, b, c, d}, then the relation: R={(a,a),(b,b),(c,c),(d,d)} is reflexive?.

If A = {1,2,3,…,9} and R is the relation in A xx A defined by (a, b) R (c, d), if a+d=b+c for (a, b), (c, d) in A xx A . Prove that R is an equivalence relation.

Write down the range of the relation R={(a,a),(a,b),(c,d),(d,b)} defined on the set {a,b,c,d} .

If Set A= .{a, b, c, d} and R = { (a, a), (a, b), (a, c), (b, c), (b, d), (c, d),(d, a)} be a relation on set A, then R is :
