domain of (2x-6)/(x+9)

domain

\frac{2 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

g (x) = 1 - x^{2}

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

3 x + \frac{6}{5}

- x + 4 - 2

f (x) = \frac{1}{x - 8}

What is the domain of (2x-6)/(x+9) ?
The domain of (2x-6)/(x+9) is x<-9\lor x>-9
