domain of g(x)=(x+9)/(x^2-16)

domain

g (x) = \frac{x + 9}{x ^{2} - 16}

x < - 4 or - 4 < x < 4 or x > 4

Interval Notation

(- \infty, - 4) \cup (- 4, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - 4

The function domain

x < - 4 or - 4 < x < 4 or x > 4

\frac{x}{7 x - 4}

f (x) = x + x + 9

\frac{3 x + 5}{2 x - 3}

\frac{x ^{2} - 3}{x ^{3}}

f (x) = \frac{1}{x ^{2} - 4}

What is the domain of g(x)=(x+9)/(x^2-16) ?
The domain of g(x)=(x+9)/(x^2-16) is x<-4\lor-4<x<4\lor x>4
