A relation R={a,b),(a,a),(a,c),(x,,x),(x,y),(y,y),(d,d),(d,c)}. Write a relation `E sub R` such that x is equal to y.

Let A={x, y, z} be a given set and a relation R on A ios defined as follows : R={(x,x),(y,y),(z,z),(x,y),(y,z),(z,x)} Then the relation R on A is -

Let R={(x,y):x^(2)+y^(2)=1,x,y in R} be a relation in R. Then the relation R is

If R={(x,y):x^(2)+y^(2)<=4;x,y in Z} is a relation on Z, write the domain of R.

If R be a relation in a set A and (x, y) in R rArr(y, x) in R AA x, y in A then the relation R is called (A) reflexive (B) symmetric (C) transitive (D) equivalence

If R be a relation in a set A and (x,y)in R rArr(y,x)in R AA x,y in A then the relation R, is called

If x=(b-c)(a-d),y=(c-a)(b-d),z=(a-b)(c-d) , then the what is x^(3)+y^(3)+z^(3) equal to?

Which of the followings are relations from {x, y, z} to {a, b, c, d} {(x, a),(x, b),(x, c), (x, d),(y, a) (y, b),(y, c),(y, d)}

Let R be a relation defined as R={(x,y) : y=sqrt((x-1)^2) , xepsilon Z and -3<=x<=3} Relation R is equals to :

Let A={a,b,c,d} and B={x,y,z} . Which of the following are relations from A to B? {(a,x),(y,d),(x,c)}
