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

domain

f (x) = \frac{1}{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

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

y = \frac{x + 8}{x ^{2} + 5}

f (x) = \frac{20}{10 + e ^{x}}

f (x) = sin (x - \frac{π}{2}) - 4

f (x) = 9 - x

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