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

domain

\frac{x ^{2} - 4 x - 12}{x + 2}

x < - 2 or x > - 2

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

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

f (x) = 16 - x^{2} + x - 3

f (x) = lo g_{10} (3) (x) + 2

\frac{x ^{2} - 7 x + 10}{x ^{2} - 5 x + 6}

f (x) = - 4 cos (2 x)

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