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

domain

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

f (x) = x^{2} - 2 x - ln (x + 1)

f (x) = \frac{1}{x ^{2}} + \frac{1}{x ^{3}}

f (x) = 15 x^{2} + 5 x - 1

f (x) = 2 x^{3} - 9 x^{2} + 12 x + 5

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