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

domain

f (x) = \frac{1}{x} 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

(2 x - 5) \cdot (2 x + 5)

f (x) = x 5 + x 2 - x + 1

f (x) = 9 ln (x + 3) (9 x) + 8

y = \frac{2 x ^{3} + x - 3}{x ^{2} + 1}

g (x) = ln (x)

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