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

domain

f (x) = \frac{x}{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) = \frac{x ^{2} - 1}{x ^{2} + 2 x - 3}

x = - 19, (6, 1)

f (x) = 8 + \frac{4}{x}

y = m x + b

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