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

domain

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

x < - 1 or - 1 < x < 0 or x > 0

Interval Notation

(- \infty, - 1) \cup (- 1, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1, x = 0

The function domain

x < - 1 or - 1 < x < 0 or x > 0

f (x) = 1 + x

lo g_{\frac{1}{5}} (x^{2} - x - 12) + 6

f (x) = \frac{( 2 - x )}{x ^{2} - x - 6}

f (x) = ln (e^{x} + 3)

\frac{2 x - 4}{14 x ^{2} - 3 x - 5}

What is the domain of f(x)= 1/(1+1/x) ?
The domain of f(x)= 1/(1+1/x) is x<-1\lor-1<x<0\lor x>0
