domain of f(x)= 1/(x(x+3))

domain

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

x < - 3 or - 3 < x < 0 or x > 0

Interval Notation

(- \infty, - 3) \cup (- 3, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 3

The function domain

x < - 3 or - 3 < x < 0 or x > 0

f (x) = 3 x^{3} - 6 x^{2} + 15 x + 21

g (x) = \frac{x}{x ^{2} + 81}

g (x) = \frac{1}{x + 5}

f (x) = - 2 (3 x)^{\frac{1}{6}}

f (x) = x + 11 + 5

What is the domain of f(x)= 1/(x(x+3)) ?
The domain of f(x)= 1/(x(x+3)) is x<-3\lor-3<x<0\lor x>0
