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

domain

f (x) = \frac{x ^{2}}{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

\frac{6 x ^{2} + x - 6}{x ^{2} - 1}

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

\frac{8 - x ^{3}}{2 x ^{2}}

(4, - 4), (- 6, - 4)

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

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