domain of f(x)=(x^2-16)/(x+4)

domain

f (x) = \frac{x ^{2} - 16}{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} - 4 x + 5

f (x) = \frac{1}{2 + x}

8 - 3 e^{x}

(2 - x) e^{- x} - 1

\frac{x ^{2} - 4 x + 4}{x ^{3} - 5 x ^{2}}

What is the domain of f(x)=(x^2-16)/(x+4) ?
The domain of f(x)=(x^2-16)/(x+4) is x<-4\lor x>-4
