domain of f(x)= 1/(4-x^2)

domain

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

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^{\frac{3}{7}}

\frac{x - 3}{x - 7} + x + 8

f (x) = x - 1

x^{2} - 3 x - 10

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

What is the domain of f(x)= 1/(4-x^2) ?
The domain of f(x)= 1/(4-x^2) is x<-2\lor-2<x<2\lor x>2
