domain of (3x)/(x^2-x-2)

domain

\frac{3 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

f (x) = sec (x - \frac{π}{4})

f (x) = 5 sin (2 x)

f (x) = 6 x^{2} - 24 x - 30

f (x) = x + \frac{100}{x}

\frac{1}{x ^{2} - 9 x}

What is the domain of (3x)/(x^2-x-2) ?
The domain of (3x)/(x^2-x-2) is x<-1\lor-1<x<2\lor x>2
