domain of f(x)=sqrt((x^2+x+1)/(x^3-x))

domain

f (x) = \frac{x ^{2} + x + 1}{x ^{3} - x}

- 1 < x < 0 or x > 1

Interval Notation

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

Solution steps

Find non-negative values for radicals:

- 1 < x < 0 or x > 1

Find undefined (singularity) points:

x = 0, x = - 1, x = 1

Combine real regions and undefined points for final function domain

- 1 < x < 0 or x > 1

What is the domain of f(x)=sqrt((x^2+x+1)/(x^3-x)) ?
The domain of f(x)=sqrt((x^2+x+1)/(x^3-x)) is -1<x<0\lor x>1
