domain of f(x)=(-x-4)/(sqrt(x^2+x))

domain

f (x) = \frac{- x - 4}{x ^{2} + x}

x < - 1 or x > 0

Interval Notation

(- \infty, - 1) \cup (0, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 1 or x \geq 0

Find undefined (singularity) points:

x = 0, x = - 1

Combine real regions and undefined points for final function domain

x < - 1 or x > 0

5 x + 3

\frac{1}{\frac{1}{x - 2} + 1}

\frac{3 x - 5}{x + 6}

\frac{4 - x}{x ^{2} - 9}

x^{4} - 5 x^{3} 9 x^{2}

What is the domain of f(x)=(-x-4)/(sqrt(x^2+x)) ?
The domain of f(x)=(-x-4)/(sqrt(x^2+x)) is x<-1\lor x>0
