domain of (-2x+63)/(x(x+9))

domain

\frac{- 2 x + 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

f (x) = - \frac{1}{x}

f (x) = 10 e^{0.1 x}

y = 3 x + 77

f (x) = 2 (x - 1)^{2} + 6

f (x) = ∣ x ∣ + 3

What is the domain of (-2x+63)/(x(x+9)) ?
The domain of (-2x+63)/(x(x+9)) is x<-9\lor-9<x<0\lor x>0
