domain of f(x)= 9/(\frac{x){9/x+9}}

domain

f (x) = \frac{9}{\frac{x}{\frac{9}{x} + 9}}

x < - 1 or - 1 < x < 0 or x > 0

Interval Notation

(- \infty, - 1) \cup (- 1, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1, x = 0

The function domain

x < - 1 or - 1 < x < 0 or x > 0

h (x) = 5^{x}

f (x) = \frac{x - 3}{x ^{2} + 9 x - 22}

y = 3

\frac{x - 5}{x - 10}

x^{2} - x + 1

What is the domain of f(x)= 9/(\frac{x){9/x+9}} ?
The domain of f(x)= 9/(\frac{x){9/x+9}} is x<-1\lor-1<x<0\lor x>0
