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

domain

\frac{x ^{3}}{x ^{2} + x - 2}

x < - 2 or - 2 < x < 1 or x > 1

Interval Notation

(- \infty, - 2) \cup (- 2, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1, x = - 2

The function domain

x < - 2 or - 2 < x < 1 or x > 1

x = - 3

f (x) = lo g_{x + 1} (2 x^{2} - 5 x + 2)

y = x^{3} + x^{2} - 20 x

y = \frac{x ^{2} + 1}{x ^{2} - 1}

f (x) = 7 + 3 x

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