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?

Let R be a relation on the set of natural numbers N, defined as: R={(x,y):y=2x,x,y in N}. Is R a function from N xxN ? If yes find the domain, co-domain and range of R.

Let R be a relation on the set of natural numbers N, defined as: R={(x,y):y=2x,x,y in N}. Is R a function from N xxN ? If yes find the domain, co-domain and range of R.

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 functions ?

A relation R defined on the set of natural no as follows R={(x,y),x+5y=20,x, y in N }.Find in domain and range of R.

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

Let R be the relation defined on the set N of natural numbers as R = {(x,y)|4x+5y=50,x,y in N} .Express R and R^-1 as set of ordered pairs

If R is a relation defined as R ={ (x,y):x,y in N and x+3y =12}. Then find the domain and range of R.

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 ?
