If R ={ (x,y) : x,y `in z, x^(2) +y^(2) le 4` } is a relation on `Z Z` then domain of R is { 0,-1,k,-2,2} find the value of k.

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)le4} is a relation in Z, then domain of R si

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

If R={(x,y):x,y in Z,x^(2)+y^(2)<=4} is a relation on Z,then domain of R is {0,1,2} b.{0,-1,-2} c.{-2,-1,0,1,2} d.none of these

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

If R={(x , y): x , y in Z , x^2+y^2lt=4} is a relation on Z, \ then domain of R is {0,1,2} b. {0,-1,-2} c. {-2,-1,0,1,2} d. none of these

If R={(x ,\ y): x^2+y^2lt=4; x ,\ y in Z} is a relation on Z , write the 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

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