domain of (63)/(x(x+9))

domain

\frac{63}{x ( x + 9 )}

x < - 9 or - 9 < x < 0 or x > 0

Interval Notation

(- \infty, - 9) \cup (- 9, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 9

The function domain

x < - 9 or - 9 < x < 0 or x > 0

in t erce pt s f (x) = 11 x^{2} + 4 y = 44

r an g e 3 sin (2 x - \frac{π}{4}) + 1

d o main f (x) = 5 x - 5

in v erse f (x) = (x - 2)^{4}

d o main f (x) = 3 \cdot 0. 2^{x}

What is the domain of (63)/(x(x+9)) ?
The domain of (63)/(x(x+9)) is x<-9\lor-9<x<0\lor x>0
