Vedclass · Answer

(A) For the function $y = \frac{1}{\sqrt{|x| - x}}$ to be defined,the expression inside the square root must be strictly positive:$|x| - x > 0$$|x| > x$We know that by definition of the absolute value function:If $x \ge 0$,then $|x| = x$,which implies $x > x$,which is impossible.If $x  x$,or $0 > 2x$,which simplifies to $x Therefore,the function is defined for all $x The domain is $( - \infty, 0)$.
