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

domain

f (x) = \frac{( x - 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

f (x) = x^{5}

X = - 8

f (x) = (x^{5} + 2)^{\frac{1}{4}}

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

y = \frac{1}{e ^{x}}

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