Popular Examples

extreme f(x)=2x^3-24x-2 extreme points

f (x) = 2 x^{3} - 24 x - 2

domain of f(x)=(x+5)/(x^3-x^2-4x+4)domain

f (x) = \frac{x + 5}{x ^{3} - x ^{2} - 4 x + 4}

domain of 3x^2+sqrt(x-5)domain

3 x^{2} + x - 5

inverse of f(4)=2x-10 inverse

f (4) = 2 x - 10

inverse of f(x)=sqrt(x^3-27)-1 inverse

f (x) = x^{3} - 27 - 1
