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

domain

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

x < - 3 or - 3 < x < 4 or x > 4

Interval Notation

(- \infty, - 3) \cup (- 3, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - 3

The function domain

x < - 3 or - 3 < x < 4 or x > 4

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

x^{3} - 3 x + 1

f (x) = \frac{x ( x + 1 )}{x - 1}

f (x) = 3 x - x^{2}

y = x^{3} + 2

What is the domain of f(x)=((2x+4))/(x^2-x-12) ?
The domain of f(x)=((2x+4))/(x^2-x-12) is x<-3\lor-3<x<4\lor x>4
