domain of f(x)= 1/(3x^2-27)

domain

f (x) = \frac{1}{3 x ^{2} - 27}

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

\frac{10}{1 + x ^{2}}

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

f (x) = 12 + x

8 x + 4 y = 32

f (x) = - x

What is the domain of f(x)= 1/(3x^2-27) ?
The domain of f(x)= 1/(3x^2-27) is x<-3\lor-3<x<3\lor x>3
