domain of (8x-1)/(x+9)

domain

\frac{8 x - 1}{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{2 ^{x} - 2 ^{- x}}{2 ^{x} + 2 ^{- x}}

f (x) = \frac{x - 7}{2}

f (x) = \frac{- x - 10}{x ^{3}}

f (x) = \frac{x - 2}{x ^{2} - 81}

What is the domain of (8x-1)/(x+9) ?
The domain of (8x-1)/(x+9) is x<-9\lor x>-9
