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

domain

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

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

in v erse f (x) = \frac{2 x}{x - 3}

d o main \frac{x}{- x + 1}

in v erse f (x) = - \frac{3}{4} + 5

d i s t an ce (0, 0), (- 9, 12)

d o main f (x) = 2 x - 10

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