domain of f(x)= 3/(1-2^x)

domain

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

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

\frac{3 x - 2}{5 - 2 x}

f (x) = x - 5 + 3

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

What is the domain of f(x)= 3/(1-2^x) ?
The domain of f(x)= 3/(1-2^x) is x<0\lor x>0
