If a set A has a relation R and `(x, y) in R implies (y, x) R AA x,y in A` then the relation `R` is called

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

Let N be the set of all natural numbers and we define a relation R={(x ,y):x, y in N , x+y is a multiple of 5} then the relation R is

Let Q be the set of all rational numbers and R be the relation defined as: R={(x,y) : 1+xy gt 0, x,y in Q} Then relation R is

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

R is a relation on the set of N defined as R= {x, y): 2x + y = 24}. Then, the domain of R is:

The relation R given by {(x, y):x^(2)-3xy+2y^(2)=0, AA x, y in R} is

Let A={0,1,2,3,4,5,6,7} ,A relation R is defined from A to A , where R= {(x,y):y=x+5,x,y in A} .Then the relation R has the range
