A relation 'R' is defined from a set A={2,3,4,5} to set B={3,6,7,10} as follows `: (x,y) in R Leftrightarrow x` divides y. Express R as a set of ordered pairs and determine the domain and range of R.

Let R be the relation on Z defined by R= {(a,b): a, b in Z, a-b is an integer}. Find the domain and range of R.

A relation R is defined on the set A = {1,2,3,4,5,6) by R = {(x,y) : y "is divisible by" x} . Verify whether R is symmetric and reflexive or not. Give reason.

The relation R defined on the set A = { 1, 2, 3, 4} by : R= {( x,y) : |x^(2)-y^(2)| le 10, x,y in A} is given by :

Check whether the relation R defined in the set {1,2,3,4,5,6,} as R={(a,b) :b= a+1} is reflexive or symmetric.

Check whether the relation R defined in the set {1,2,3,4,5,6} as R{(a,b): b=a+1)} is reflecxive or symmetric.

Let R be a relation defined on the set of natural numbers N as follow : R= {(x,y):x in N, y in N and 2x+y=24} Find the domain and range of the relation R. Also, find R is an equivalence relation or not.

If A={1,2,3,4},B={5,6}.Define a relation R from A to B by R={(x,y):x in A,y in B,x-y is odd} .Write R in the roaster form.Write down its domain and range.

If R is a relation from a set A to a set B and S is a relation from B to a set C, then the relation SoR

Determine whether the relation R in the set A = {1,2,3,4,5,6} as R = {(x,y) : y is divisible by x} is reflexive, symmetric and transitive.
