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

domain

f (x) = \frac{1}{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

\frac{3}{4}

f (x) = - x^{6}

f (x) = \frac{5 x - 10}{- 2 x ^{2} - 6 x + 20}

f (x) = \frac{2}{9} x + \frac{8}{9}

f (x) = 16 - x^{2} + x + 2

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