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

domain

f (x) = \frac{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

f (x) = cos (2 x)

y = - 7 x + 2

f (x) = 8 x - x^{2}

f (x) = \frac{x ^{2} - 4}{x - x ^{3}}

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

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