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

domain

f (x) = \frac{x}{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

lo g_{10} (6) (x^{2} - 16)

f (x) = \frac{x + 4}{x + 3}

- x^{2} + 2 x - 2

y = \frac{2 + x}{3 - x}

- x^{2} - 6 x + 9

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