Question

Find the domain of $y=\frac{1}{\sqrt{(|x|-x)}}$

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

The given function is defined for those values of x for which |x| -x $>$ 0, i.e. |x|$>$ x. this inequality is satisfied only if x$<$ 0. Hence the domain of the given function is $(-\infty ,0).$
