domain of f(x)=(2x^3)/(x^2-4)

domain

f (x) = \frac{2 x ^{3}}{x ^{2} - 4}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 2, x = - 2

The function domain

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

f (x) = x - 36

\frac{2 x - 6}{x + 3}

y = - x^{2} - 8

f (x) = \frac{x ^{2} - 5 x + 6}{x ^{2} - 4}

y = \frac{2 x - 4}{x ^{2} - 4}

What is the domain of f(x)=(2x^3)/(x^2-4) ?
The domain of f(x)=(2x^3)/(x^2-4) is x<-2\lor-2<x<2\lor x>2
