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

Solution

domain

\frac{3 x}{x + 4}

Solution

x < - 4 or x > - 4

+1

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

Popular Examples

inverse of f(x)=sqrt(6x)inverse

f (x) = 6 x

extreme f(x)=x^4-4x^3+3 extreme points

f (x) = x^{4} - 4 x^{3} + 3

asymptotes of y=(2x^2+x-6)/(x^2+x-30)asymptotes

y = \frac{2 x ^{2} + x - 6}{x ^{2} + x - 30}

inverse of f(x)=6x^{1/4}+5 inverse

f (x) = 6 x^{\frac{1}{4}} + 5

slope ofintercept x-y=7 slope intercept

x - y = 7
