Solution

x < - 1 or x > - 1

+1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

Popular Examples

domain of f(x)=sqrt(t)-5 domain

f (x) = t - 5

domain of f(x)=(2x+5)/(sqrt(x^2+2x-48))domain

f (x) = \frac{2 x + 5}{x ^{2} + 2 x - 48}

domain of \sqrt[3]{sqrt(2x-4)-3}domain

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

f (x) = \frac{∣ x - 2 ∣}{x - 2}

domain of y=ln(x+2)domain

y = ln (x + 2)
