domain of f(x)=(20x+99)/(x(x+11))

domain

f (x) = \frac{20 x + 99}{x ( x + 11 )}

x < - 11 or - 11 < x < 0 or x > 0

Interval Notation

(- \infty, - 11) \cup (- 11, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 11

The function domain

x < - 11 or - 11 < x < 0 or x > 0

What is the domain of f(x)=(20x+99)/(x(x+11)) ?
The domain of f(x)=(20x+99)/(x(x+11)) is x<-11\lor-11<x<0\lor x>0
