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

Solution

extreme points

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

Solution

Minimum (1, - 2)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 1

into

x^{2} - 2 x - 1 : - 2

Minimum (1, - 2)

Popular Examples

extreme f(x)=xy+8/x+8/y extreme points

f (x) = x y + \frac{8}{x} + \frac{8}{y}

extreme f(x,y)=ln(xy-1)extreme points

f (x, y) = ln (x y - 1)

extreme f(x)=3x^3-6x^2+1 extreme points

f (x) = 3 x^{3} - 6 x^{2} + 1

extreme f(x)=x^4-x^3-6x^2 extreme points

f (x) = x^{4} - x^{3} - 6 x^{2}

extreme f(x)= 1/(x^2+2x+9)extreme points

f (x) = \frac{1}{x ^{2} + 2 x + 9}
