Let relation R defined on Z as follows R={(x,y),x in Z,y in Z,x^(2)=y^(2)), then find domain of R.

If R={(x,y)//x,y in Z, x^(2)+y^(2)le4} is a relation in Z, then domain of R si

If R={(x,y):x,y in Z,x^(2)+y^(2)<=4} is a relation defined on the set Z of integers,then write domain of R.

If R={(x,y):x,y in Z,x^(2)+3y^(2)<=8} is a relation on the set of integers Z ,then the domain of R^(-1) is

Which of the following represent functions? (a){(x,y):y^(2)=4ax,x,y varepsilon}(b){(x,y):y=|x|,x,y varepsilon R}(c){(x,y):x^(2)+y^(2)=1,x,y varepsilon R}(d.){(x,y):x^(2)-y^(2)=1,x

If R ={ (x,y) : x,y in z, x^(2) +y^(2) le 4 } is a relation on Z then domain of R is

If R ={(x,y): x,y in Z , x^2 +y^2 =64} then , write R in the roaster form

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 :

If R= {(x,y):x, y in Z, x^2+y^2le9} is a realation on Z, then domain of R is:
