Solution

x < 3 or x > 3

+1

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

Popular Examples

inverse of f(x)=(3^x+5)/9 inverse

f (x) = \frac{3 ^{x} + 5}{9}

inverse of f(x)=-1/(x-1)+3 inverse

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

extreme (x^2-7)/(x-4)extreme points

\frac{x ^{2} - 7}{x - 4}

inverse of f(x)=5x^2-3 inverse

f (x) = 5 x^{2} - 3

inverse of y=4x-x^2 inverse

y = 4 x - x^{2}
