domain of f(x)=((x-6))/(x+9)

domain

f (x) = \frac{( x - 6 )}{x + 9}

x < - 9 or x > - 9

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 9

The function domain

x < - 9 or x > - 9

f (x) = \frac{( - x ^{2} + 1 )}{( x ^{2} + 2 x - 3 )}

\frac{1}{11 ( \frac{1}{11 x - 1} ) - 1}

f (x) = \frac{2 x}{1 - x}

x + 1 + 2 x

g (x) = 16 - x^{2}

What is the domain of f(x)=((x-6))/(x+9) ?
The domain of f(x)=((x-6))/(x+9) is x<-9\lor x>-9
