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

domain

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

- 1 < x \leq 0 or x > 1

Interval Notation

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

Solution steps

Find non-negative values for radicals:

- 1 < x \leq 0 or x > 1

Find undefined (singularity) points:

x = 1, x = - 1

Combine real regions and undefined points for final function domain

- 1 < x \leq 0 or x > 1

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