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

domain

f (x) = \frac{e ^{x} - 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

(4, 1), (8, - 4)

f (x) = \frac{4 x}{x - 5}

f (x) = 4 x^{2} - 8 x - 1

10 x - 9

(1, 2), (4, 4)

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