Let `R={(x,y):x,yepsilonA,x+y=5}` where `A={1,2,3,4,5}` then `R` is

Let R={(x,y):x,y in A,x+y=5} where A= { 1,2,3,4,5} then

Let R ={(x,y) : x,y in A, x+y=5} , where A= {1,2,3,4,5}. Then :

Let R be a relation on the set of natural numbers ,defined as R ={(x,y):x+2y=20, x,y varepsilon N} and x varepsilon {1,2,3,4,5} .Then ,the range of R is :

Let R={(x,y):|x^(2)-y^(2)|<1} be a relation on set A={1,2,3,4,5}. Write R as a set of ordered pairs.

Let R be a Relation in the set A={1,2,3,4,5,6} define as R={(x,y):y=2x-1} Write R in roster form and find it's domain and range
