The domain of the function f(x) = 1/√(|x| - x) is

- (0,∞)
- (-∞,0)
- (-∞,∞)
- (-∞,∞) - {0}

**Solution**

f(x) = 1/√(|x| - x)

|x| - x > 0

|x| > x

⇒ x < 0

**The correct option is B.**

The domain of the function f(x) = 1/√(|x| - x) is

- (0,∞)
- (-∞,0)
- (-∞,∞)
- (-∞,∞) - {0}

**Solution**

f(x) = 1/√(|x| - x)

|x| - x > 0

|x| > x

⇒ x < 0

**The correct option is B.**
