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

y = \frac{x - 4}{x ^{2} - 16}

y = \frac{1}{x - 9}

3 - 2 x^{2} - x

\frac{ln ( 5 x )}{x}

9 - x + 4

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
