domain of (4x)/(x-3)

Solution

domain

\frac{4 x}{x - 3}

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

inflection f(x)=e^{-2x^2}inflection points

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

extreme f(x)=5x^2-15x extreme points

f (x) = 5 x^{2} - 15 x

asymptotes of f(x)=(6x-7)/(x-4)asymptotes

f (x) = \frac{6 x - 7}{x - 4}

distance (-2,-3),(4,0)distance

(- 2, - 3), (4, 0)

inverse of f(x)=(x+4)^{1/4}inverse

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