domain of f(x)=(x+2)/(x+9)

domain

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

f (x) = x + 1 - 1

y = arccos (\frac{1}{x - 3})

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

f (x) = \frac{( 5 ln ( x ) )}{x ^{3}}

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