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

domain

\frac{x ^{3}}{x + 1}

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

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

f (x) = 10 x - 4

f (x) = \frac{x + 1}{x ^{2} - 4}

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

\frac{1}{1 + 2 I}
