Question

( sqrt{4-x^{2}} )
( 4-x^{2} geq 0 quad x^{2}-4 leq 0 )
( (9+2(2+x) geqslant 0 quad(x-2)(x+2) times 0 )
( leqslant-frac{1}{2}+frac{1}{2}-frac{1}{2}+frac{1}{2} )
( frac{2}{1}+(-22] )
( sqrt{(sin x)-sin x} geq 0 )
( |sin x|-sin x geq 2 )
( |sin x|>sin x cdot ) alurays
( D in R )
( D=D_{1} cap D_{2} )
( D=[-2,2] )

# 3. Iff(x) =V4-x+ - lsin xl- sin x , then the domain off(x)is (1)(-2,0] (3) (-2,2} (2)(0,2] (4)[-2
