Answer 2

Answer:

Can't be defined.

Step-by-step explanation:

Given f(x) = $\dfrac{1}{\sqrt{x-|x|}}$

   For Domain of this function, f(x) must be a real number.

⇒ $\dfrac{1}{\sqrt{x-|x|}}$ must be a real number

      x - | x | shouldn't be -ve, otherwise it will not be a real number.

    If x - | x | = 0, denominator will be 0 and f(x) will become undefined. So:

   For a real number x - | x | should be greater than 0

⇒ x - | x | > 0

⇒ x > | x |

   But for any number, | x | > x.

therefore domain of this function is not defined.
