domain of 1/(x^2-4)

Solution

domain

\frac{1}{x ^{2} - 4}

Solution

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

+1

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

Popular Examples

domain of f(x)=(sin(x))/x domain

f (x) = \frac{sin ( x )}{x}

range of y=cos(x+1)range

y = cos (x + 1)

domain of f(x)=\sqrt[4]{|x|-|x+2|}domain

inverse of f(x)= x/(x+6)inverse

f (x) = \frac{x}{x + 6}

shift f(x)=sin(3x-2pi)shift

f (x) = sin (3 x - 2 π)
