domain of f(x)=-3/(x+1)-1

domain

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

f (x) = (x + 5)^{2}

f (x) = \frac{1}{81 - x ^{2}}

2 + lo g_{3} (x)

f (x) = sec (x)

What is the domain of f(x)=-3/(x+1)-1 ?
The domain of f(x)=-3/(x+1)-1 is x<-1\lor x>-1
