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

domain

(x - 1) e^{- \frac{1}{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{- x ^{2} + 2 x + 15}{x + 3}

ln (\frac{2 + x}{2 - x})

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

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

f (x) = 8 + 7 x - 8

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