domain of f(x)=(x^2-11x-12)/(x+4)

domain

f (x) = \frac{x ^{2} - 11 x - 12}{x + 4}

x < - 4 or x > - 4

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

f (x) = x^{2} + 8 x + 1

y = - 2 x

\frac{20 x ^{3} + 30 x ^{2}}{15 x ^{5}}

f (x) = - 2 x + 2

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

What is the domain of f(x)=(x^2-11x-12)/(x+4) ?
The domain of f(x)=(x^2-11x-12)/(x+4) is x<-4\lor x>-4
