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

domain

\frac{8 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) = x^{2} + 2 x + 5

x^{2} + 4

\frac{x + 8}{x ^{3} + x - 1}

\frac{x - 3}{2}

\frac{1}{5} x - \frac{9}{5}

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