domain of g(x)=(8x)/(x^2-9)

domain

g (x) = \frac{8 x}{x ^{2} - 9}

x < - 3 or - 3 < x < 3 or x > 3

Interval Notation

(- \infty, - 3) \cup (- 3, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3, x = - 3

The function domain

x < - 3 or - 3 < x < 3 or x > 3

5^{- x} + 1

x^{2} + 5 x - 14

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

f (x) = \frac{1}{tan ( x )}

y = 5 x - 5

What is the domain of g(x)=(8x)/(x^2-9) ?
The domain of g(x)=(8x)/(x^2-9) is x<-3\lor-3<x<3\lor x>3
