+1

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

domain of (x^2-9x+20)/(4x^2-12x-40)domain

\frac{x ^{2} - 9 x + 20}{4 x ^{2} - 12 x - 40}

domain of y=cos(x)domain

y = cos (x)

domain of f(x)=3-10^{x-1}domain

f (x) = 3 - 1 0^{x - 1}

domain of f(x)=(sqrt(x-4))/(sqrt(x^2-9))domain

f (x) = \frac{x - 4}{x ^{2} - 9}

domain of f(x)=(sqrt(5-x))/(x+6)domain

f (x) = \frac{5 - x}{x + 6}
