domain of f(x)=-5/(x^2+3x)

domain

f (x) = - \frac{5}{x ^{2} + 3 x}

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

What is the domain of f(x)=-5/(x^2+3x) ?
The domain of f(x)=-5/(x^2+3x) is x<-3\lor-3<x<0\lor x>0
