domain of f(x)=(x+1/x)^3

domain

f (x) = (x + \frac{1}{x})^{3}

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) = n - arcsin (1 - 2 x)

f (x) = lo g_{3} (x + 4)

f (x) = ln (2 - 3 x)

x x^{2} - 2

2 x^{2} - 7 x + 3

What is the domain of f(x)=(x+1/x)^3 ?
The domain of f(x)=(x+1/x)^3 is x<0\lor x>0
