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

domain

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

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

f (x) = \frac{18 x ^{2}}{9 x ^{2} + 5}

1 + x^{2}

- x^{3} + 9 x^{2} - 27 x + 8

\frac{1}{t}

\frac{1 + sin ( x )}{x + cos ( x )}

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