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

domain

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

x < 0

Interval Notation

(- \infty, 0)

Solution steps

Find non-negative values for radicals:

x \leq 0

Find undefined (singularity) points:

x = 0

Combine real regions and undefined points for final function domain

x < 0

- x^{2} + 14 x - 43

- - 2 x + 5

f (x) = \frac{( ln ( x ) )}{x}

\frac{3}{x ^{2} + 1}

\frac{x ^{2} + 12 x + 36}{x ^{2} - 36}
