domain of f(x)=((x+1))/(x^2-4x-12)

domain

f (x) = \frac{( x + 1 )}{x ^{2} - 4 x - 12}

x < - 2 or - 2 < x < 6 or x > 6

Interval Notation

(- \infty, - 2) \cup (- 2, 6) \cup (6, \infty)

Solution steps

Find undefined (singularity) points:

x = 6, x = - 2

The function domain

x < - 2 or - 2 < x < 6 or x > 6

What is the domain of f(x)=((x+1))/(x^2-4x-12) ?
The domain of f(x)=((x+1))/(x^2-4x-12) is x<-2\lor-2<x<6\lor x>6
