domain of f(x)= 5/(9-x^2)

domain

f (x) = \frac{5}{9 - x ^{2}}

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

f (x) = \frac{x - 2}{x + 9}

y = \frac{x - 4}{x ^{2} - 16}

y = \frac{1}{x - 9}

3 - 2 x^{2} - x

\frac{ln ( 5 x )}{x}

What is the domain of f(x)= 5/(9-x^2) ?
The domain of f(x)= 5/(9-x^2) is x<-3\lor-3<x<3\lor x>3
