Popular Examples

domain of (x^2+x+1)/x domain

\frac{x ^{2} + x + 1}{x}

domain of f(x)=(x-4)/(x^2+8x+16)domain

f (x) = \frac{x - 4}{x ^{2} + 8 x + 16}

domain of f(x)=(3+|x|)/(2x^2+5x-3)domain

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

extreme f(x)=-x^2+3 extreme points

f (x) = - x^{2} + 3

asymptotes of (4x^2)/(x^2+4)asymptotes
