domain of f(x)=(9x)/(x^2-1)

domain

f (x) = \frac{9 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

(13 - x)^{\frac{1}{6}}

(1, 4), (3, 6)

f (x) = x - 4

\frac{2 x + 3}{x - 1}

x - 6

What is the domain of f(x)=(9x)/(x^2-1) ?
The domain of f(x)=(9x)/(x^2-1) is x<-1\lor-1<x<1\lor x>1
