domain of (x^2-x)/(x^2-1)

domain

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

x < - 1 or - 1 < x < 1 or x > 1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 1, x = - 1

The function domain

x < - 1 or - 1 < x < 1 or x > 1

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

x^{2} + 3

f (x) = x^{2} + 5 x + 6

f (x) = 1.1011 E 13

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

What is the domain of (x^2-x)/(x^2-1) ?
The domain of (x^2-x)/(x^2-1) is x<-1\lor-1<x<1\lor x>1
