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

domain

f (x) = \frac{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

y = 8 x - 7, (4, - 5)

f (x) = \frac{x ^{2} - 3 x - 10}{x - 2}

f (x) = \frac{x}{x ^{2} + 15 x + 50}

y = lo g_{4} (x)

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