extreme f(x)=3x^2-18x+23

Solution

extreme points

f (x) = 3 x^{2} - 18 x + 23

Solution

Minimum (3, - 4)

Solution steps

f^{'} (x) = 6 x - 18

Find intervals:

Decreasing

: - \infty < x < 3,

Increasing

: 3 < x < \infty

Plug

x = 3

into

3 x^{2} - 18 x + 23 : - 4

Minimum (3, - 4)

Popular Examples

extreme f(x,y)=5+3x^2+3y^2+2y^3+x^3 extreme points

f (x, y) = 5 + 3 x^{2} + 3 y^{2} + 2 y^{3} + x^{3}

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

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

extreme f(x)=3x^3-9x+3 extreme points

f (x) = 3 x^{3} - 9 x + 3

extreme y=x^3+x^2-x+8 extreme points

y = x^{3} + x^{2} - x + 8

extreme f(x)=3xsqrt(8-x^2)extreme points

f (x) = 3 x 8 - x^{2}
