domain of f(x)= 3/(1-e^x)

domain

f (x) = \frac{3}{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

3 x^{2} - 2 x - 6

3 (\frac{1}{2})^{x}

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

f (x) = x^{2} + 2 x - 1, x > 0

g (x) = 4 x - 6

What is the domain of f(x)= 3/(1-e^x) ?
The domain of f(x)= 3/(1-e^x) is x<0\lor x>0
