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

domain

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

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

Solution steps

Find undefined (singularity) points:

x = 1, x = - 1

The function domain

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

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

f (x) = \frac{2 x ^{2} - 8}{- x ^{2} - 2 x + 3}

g (x) = \frac{9 + x}{8 - x}

\frac{x - 7}{3 x - 5}

f (x) = 5 x^{3} - 3 x^{4}

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