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^{2} + 25

f (x) = - x^{2} - 1

cot (x)

f (x) = 2 x - 3

f (x) = x^{2} - 6 x + 4

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
