domain of x+1/x+1/(x+1/x)

domain

x + \frac{1}{x} + \frac{1}{x + \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

e^{2 x^{2}}

f (x) = \frac{8 + x}{e ^{c o s (x)}}

- 12 + 12 x - 3 x^{2}

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

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

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