domain of f(x)=((e^x))/(1-e^x)

domain

f (x) = \frac{( e ^{x} )}{1 - e ^{x}}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

x - \frac{1}{x}

f (x) = - 3 x^{2} + 9 x + 5

- 2 x + 10

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

f (x) = \frac{2 x - 4}{x - 7}

What is the domain of f(x)=((e^x))/(1-e^x) ?
The domain of f(x)=((e^x))/(1-e^x) is x<0\lor x>0
