extreme f(x)=x^2-4x-5

Solution

extreme points

f (x) = x^{2} - 4 x - 5

Solution

Minimum (2, - 9)

Solution steps

f^{'} (x) = 2 x - 4

Find intervals:

Decreasing

: - \infty < x < 2,

Increasing

: 2 < x < \infty

Plug

x = 2

into

x^{2} - 4 x - 5 : - 9

Minimum (2, - 9)

Popular Examples

extreme f(x,y)=x^2-4xy+y^2+6y+2 extreme points

f (x, y) = x^{2} - 4 x y + y^{2} + 6 y + 2

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

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

extreme f(x)= 10/3 x^3+13x^2+12x+50 extreme points

f (x) = \frac{10}{3} x^{3} + 13 x^{2} + 12 x + 50

extreme 9-2x+4y-x^2-4y^2 extreme points

9 - 2 x + 4 y - x^{2} - 4 y^{2}

extreme f(x)=6x+2xy-2y-2x^2-y^2 extreme points

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