domain of f(x)=((x+1/x+11))/(x+1/x+2)

domain

f (x) = \frac{( x + \frac{1}{x} + 11 )}{x + \frac{1}{x} + 2}

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) = \frac{1}{4} x - \frac{1}{2}

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

- \frac{cos ( π \frac{11 x}{6} )}{2} - 2

f (x) = \frac{1}{9 - t}

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

What is the domain of f(x)=((x+1/x+11))/(x+1/x+2) ?
The domain of f(x)=((x+1/x+11))/(x+1/x+2) is x<-1\lor-1<x<0\lor x>0
