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

domain

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

x < - 1 or - 1 < x < 2 or x > 2

Interval Notation

(- \infty, - 1) \cup (- 1, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 1

The function domain

x < - 1 or - 1 < x < 2 or x > 2

y = sec (x - π)

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

\frac{1}{2} x

- 1 - x + 3

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

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