Let N be the set of natural numbers and the relation R be defined on N such that R = {(x, y) : y = 2x, x, y in N} . Is this relation a function ?

Let N be the set of natural numbers and the relation R be defined on N such that R = {(x , y) : y = 2x , x , y in N} .What is the domain, codomain and range of R? Is this relation a function?

If A={x:x in N,x<=8} and R is a relation on A such that R={(x,y):x in A,y in A,y=2x}. Find domain and range of R.

A = {(1,2,3,......10} The relation R defined in the set A as R = {(x,y) : y = 2x} . Show that R is not an equivalence relation.

In the set A = {1, 2, 3, 4, 5} , a relation R is defined by R = {(x, y) \ x, y in A and x < y} . Then R is
