A) {0, 1, 2}
B) {0, - 1, - 2}
C) {- 2, - 1, 0, 1, 2}
D) None of these
Correct Answer: C
Solution :
\[\because \,R=\{(x,\,y)|x,\,y\in Z,\,{{x}^{2}}+{{y}^{2}}\le 4\}\] \[\therefore \] \[R=\{(-2,\,0),(-1,\,0),(-1,\,1),(0,\,-1)(0,\,1),(0,\,2),(0,-2)\]\[(1,\,0),(1,\,1),(2,\,0)\}\] Hence, Domain of\[R=\{-2,\,-1,\,0,\,1,\,2\,\}\].
