domain of f(x)=(x-6)/(x^2-x-2)

domain

f (x) = \frac{x - 6}{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

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

f (x) = lo g_{\frac{1}{3}} (2 x^{2} - 12 x + 22)

f (x) = \frac{5 - x}{x + 8}

f (x) = 1 - sin (x)

x^{2} - 3 x - 4

What is the domain of f(x)=(x-6)/(x^2-x-2) ?
The domain of f(x)=(x-6)/(x^2-x-2) is x<-1\lor-1<x<2\lor x>2
