extreme f(x)=x^2-8x+9

Solution

extreme points

f (x) = x^{2} - 8 x + 9

Solution

Minimum (4, - 7)

Solution steps

f^{'} (x) = 2 x - 8

Find intervals:

Decreasing

: - \infty < x < 4,

Increasing

: 4 < x < \infty

Plug

x = 4

into

x^{2} - 8 x + 9 : - 7

Minimum (4, - 7)

extreme f(x,y)=x^3-y^3+6xy extreme points

f (x, y) = x^{3} - y^{3} + 6 x y

extreme f(x,y)=288y^2+x^2-x^2y extreme points

f (x, y) = 288 y^{2} + x^{2} - x^{2} y

extreme f(x,y)=x(x-4)y(y-4)extreme points

f (x, y) = x (x - 4) y (y - 4)

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

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

extreme f(x)=2x^3-3x^2-12x-3 extreme points

f (x) = 2 x^{3} - 3 x^{2} - 12 x - 3
