Solution

domain

\frac{4}{x ^{2} - 9}

Solution

x < - 3 or - 3 < x < 3 or x > 3

+1

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

Popular Examples

domain of y=tan(3x)domain

y = tan (3 x)

domain of (2x^2)/(1-x^2)domain

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

domain of y=2x^2+4x-6 domain

y = 2 x^{2} + 4 x - 6

domain of f(x)=-2/x domain

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

domain of f(x)=x^2ln(4+6x)domain

f (x) = x^{2} ln (4 + 6 x)
