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

domain

f (x) = 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

f (x) = e^{x^{2}}

y = \frac{x}{x + 1}

y = 2 (x + 3) (x - 7)

X^{3}

f (x) = 3 - 2 x

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