extreme f(x)=3x^2-36x+81

Solution

extreme points

f (x) = 3 x^{2} - 36 x + 81

Solution

Minimum (6, - 27)

Solution steps

f^{'} (x) = 6 x - 36

Find intervals:

Decreasing

: - \infty < x < 6,

Increasing

: 6 < x < \infty

Plug

x = 6

into

3 x^{2} - 36 x + 81 : - 27

Minimum (6, - 27)

Popular Examples

extreme K(r,s)=3r-4s extreme points

K (r, s) = 3 r - 4 s

extreme f(9)= t/(t-4)extreme points

f (9) = \frac{t}{t - 4}

extreme 2x^2+8x-1 extreme points

2 x^{2} + 8 x - 1

extreme f(x,y)=x^{3/4}y^{1/4}extreme points

f (x, y) = x^{\frac{3}{4}} y^{\frac{1}{4}}

extreme x^3-3x^2+6x-6 extreme points

x^{3} - 3 x^{2} + 6 x - 6
