domain of f(x)=(3(x-2))/(x^2-4)

domain

f (x) = \frac{3 ( x - 2 )}{x ^{2} - 4}

x < - 2 or - 2 < x < 2 or x > 2

Interval Notation

(- \infty, - 2) \cup (- 2, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 2

The function domain

x < - 2 or - 2 < x < 2 or x > 2

f (x) = (x - 2)^{2} (x - 1)

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

y = \frac{1}{4 x ^{2} - 4 x - 3}

\frac{x ^{2} - 4 x - 12}{x + 2}

f (x) = 4 x^{2} + 1

What is the domain of f(x)=(3(x-2))/(x^2-4) ?
The domain of f(x)=(3(x-2))/(x^2-4) is x<-2\lor-2<x<2\lor x>2
