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

domain

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

x < - 8 or x > - 8

Interval Notation

(- \infty, - 8) \cup (- 8, \infty)

Solution steps

Find undefined (singularity) points:

x = - 8

The function domain

x < - 8 or x > - 8

f (x) = ln (x^{3} - 12 x)

\frac{x - 1}{x ^{2} + 5}

f (x) = \frac{16 - x ^{2}}{x - 3}

f (x) = \frac{x ^{2} - 2 x - 24}{x ^{2} - 25}

f (x) = \frac{x + 5}{x ^{2} - 7 x + 10}

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