R=\left\{(x, y): x, y \in Z, x^2+y^2 \leq 4\right\}

is a relation in

Z

, then domain of

R

View answer and explanation

Correct option: C

\{-2,-1,0,1,2\}

Option C ({-2, -1, 0, 1, 2}) is correct because the domain of R consists of all integer values of x for which there exists an integer y such that

x^2 + y^2 \leq 4

f(x)=x(4-x)

f^{-1}(x)

g(f(x))=|\sin x|

f(g(x))=(\sin \sqrt{x})^2

f:\left( {2,\;3} \right) \to \left( {0,\;1} \right)

f\left( x \right) = x - \left[ x \right]

f(x)=x^4

f(x)=(x+1)^2-1(x \geq-1)
