domain of (x^3)/(2(1+x))

domain

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

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{x}{x ^{2} - 1}

\frac{7 x}{x + 3}

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

f (x) = lo g_{4} (x - 9)

What is the domain of (x^3)/(2(1+x)) ?
The domain of (x^3)/(2(1+x)) is x<-1\lor x>-1
