domain of f(x)=(x+2)/(x^3)

domain

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

\frac{6 x ^{2} + 35 x - 6}{4 x ^{2} + 23 x - 6}

\frac{x ^{2} - 16}{x ^{2} - 10 x + 16}

f (x) = \frac{15 x ^{2}}{x + 5}

f (x) = y - 5 x y + 5 x = 1

What is the domain of f(x)=(x+2)/(x^3) ?
The domain of f(x)=(x+2)/(x^3) is x<0\lor x>0
