extreme f(x)=9x^2-72x+108

Solution

extreme points

f (x) = 9 x^{2} - 72 x + 108

Solution

Minimum (4, - 36)

Solution steps

f^{'} (x) = 18 x - 72

Find intervals:

Decreasing

: - \infty < x < 4,

Increasing

: 4 < x < \infty

Plug

x = 4

into

9 x^{2} - 72 x + 108 : - 36

Minimum (4, - 36)

Popular Examples

extreme x^4+3x^3-6 extreme points

x^{4} + 3 x^{3} - 6

extreme f(x,y)=x^2-14x+y^2-16y extreme points

f (x, y) = x^{2} - 14 x + y^{2} - 16 y

extreme f(x)=x^3-5x+4 extreme points

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

extreme f(x)=8x+4 extreme points

f (x) = 8 x + 4

extreme f(x)=cos(2(x-60))-1 extreme points

f (x) = cos (2 (x - 6 0^{\circ})) - 1
