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

domain

f (x) = \frac{x ^{3}}{x + 2}

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

f (x) = \frac{2 x ^{2} + 1}{\frac{1}{16} x ^{2} + 3}

y = \frac{3 x}{x + 1}

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

f (x) = \frac{4 x + 8}{x ^{2} + 4 x - 32}

\frac{2}{9 x}

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