domain of f(x)= 4/(1-e^x)

domain

f (x) = \frac{4}{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

\frac{4 - x}{x ( x - 3 )}

y = - \frac{1}{4} x + 2

- \frac{1}{2 7 - x}

\frac{x - 6}{x ^{2} - 25}

f (x) = - 4 x^{2} + 12

What is the domain of f(x)= 4/(1-e^x) ?
The domain of f(x)= 4/(1-e^x) is x<0\lor x>0
