Solution

x < - 4 or x > - 4

+1

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

Popular Examples

domain of f(x)=(5x)/(sqrt(3x^2-12))domain

f (x) = \frac{5 x}{3 x ^{2} - 12}

domain of f(x)=2^{x-1}+1 domain

f (x) = 2^{x - 1} + 1

domain of (3.5x^2-6)/(x+2)domain

\frac{3.5 x ^{2} - 6}{x + 2}

domain of f(x)= 8/(x+8)domain

f (x) = \frac{8}{x + 8}

domain of y=sqrt(4x-28)domain

y = 4 x - 28
