domain of f(x)=(8x)/(x+9)

domain

f (x) = \frac{8 x}{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}{x + 9}

f (x) = x x + 21

f (x) = \frac{x + 5}{- 5}

(0, 0), (2, 5)

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

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