JEE Math Practice Question
If the functions are defined as $$f(x) = \sqrt x $$ and $$g(x) = \sqrt {1 - x} $$, then what is the common domain of the following functions : f + g, f $$-$$ g, f/g, g/f, g $$-$$ f where $$(f \pm g)(x) = f(x) \pm g(x),(f/g)x = {{f(x)} \over {g(x)}}$$
- A.$$0 \le x \le 1$$
- B.$$0 \le x < 1$$
- C.$$0 < x < 1$$
- D.$$0 < x \le 1$$
