domain of f(x)=-1/(sqrt(x))

domain

f (x) = - \frac{1}{x}

x > 0

Interval Notation

(0, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 0

Find undefined (singularity) points:

x = 0

Combine real regions and undefined points for final function domain

x > 0

\frac{x ^{2} - 4}{3 x - 6}

x^{2} - 4 x - 12

- x^{2} - 8 x - 17

f (x) = 2 sin (- 2 x + 55665)

2 x^{3} - 5

What is the domain of f(x)=-1/(sqrt(x)) ?
The domain of f(x)=-1/(sqrt(x)) is x>0
