x = 0

The function domain

x < 0 or x > 0

Popular Examples

domain of (x^3)/(\sqrt[3]{1-x^3)}domain

inflection 1/3 x^3+x^2-3x-5 inflection points

\frac{1}{3} x^{3} + x^{2} - 3 x - 5

domain of f(x)=x-1/x domain

f (x) = x - \frac{1}{x}

extreme f(x)=x^2(x-2)^2(x-1)^2 extreme points

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

asymptotes of f(x)=((x^2+1))/(x^3+1)asymptotes

f (x) = \frac{( x ^{2} + 1 )}{x ^{3} + 1}
