domain of f(x)=(x^2-x-12)/(x^2+x-6)

domain

f (x) = \frac{x ^{2} - x - 12}{x ^{2} + x - 6}

x < - 3 or - 3 < x < 2 or x > 2

Interval Notation

(- \infty, - 3) \cup (- 3, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 3

The function domain

x < - 3 or - 3 < x < 2 or x > 2

What is the domain of f(x)=(x^2-x-12)/(x^2+x-6) ?
The domain of f(x)=(x^2-x-12)/(x^2+x-6) is x<-3\lor-3<x<2\lor x>2
