domain of f(x)= 1/(x^2)-1/x

domain

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

(2, 8), (4, 5)

f (x) = ln (x^{2} - 4)

(4, - 3), (- 2, - 3)

\frac{6}{7 + x}

- \frac{1}{4} x^{3}

What is the domain of f(x)= 1/(x^2)-1/x ?
The domain of f(x)= 1/(x^2)-1/x is x<0\lor x>0
