domain of (e^x+1)/(e^x-1)

domain

\frac{e ^{x} + 1}{e ^{x} - 1}

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 - 5 ) ^{2}}{( x + 3 )}

f (x) = \frac{1}{x - 2} + \frac{5}{x + 1}

+ x^{3} - 5 x

t + 5

(\frac{x ^{2}}{4} - \frac{x}{2} - \frac{1}{4})^{2}

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