extreme x^3-6x^2+2x+4

Solution

extreme points

x^{3} - 6 x^{2} + 2 x + 4

Solution

Maximum (\frac{6 - 30}{3}, \frac{288 - 52 30}{9} + 830 - 40), Minimum (\frac{6 + 30}{3}, \frac{288 + 52 30}{9} - 40 - 830)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - \frac{10}{3} + 2,

Decreasing

: - \frac{10}{3} + 2 < x < \frac{10}{3} + 2,

Increasing

: \frac{10}{3} + 2 < x < \infty

Plug

x = \frac{6 - 30}{3}

into

x^{3} - 6 x^{2} + 2 x + 4 : \frac{288 - 52 30}{9} + 830 - 40

Maximum (\frac{6 - 30}{3}, \frac{288 - 52 30}{9} + 830 - 40)

Plug

x = \frac{6 + 30}{3}

into

x^{3} - 6 x^{2} + 2 x + 4 : \frac{288 + 52 30}{9} - 40 - 830

Minimum (\frac{6 + 30}{3}, \frac{288 + 52 30}{9} - 40 - 830)

Maximum (\frac{6 - 30}{3}, \frac{288 - 52 30}{9} + 830 - 40), Minimum (\frac{6 + 30}{3}, \frac{288 + 52 30}{9} - 40 - 830)

extreme f(x,y)=x^2+9xy+y^2 extreme points

f (x, y) = x^{2} + 9 x y + y^{2}

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

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

extreme f(x)=-7x^3+21x+5 extreme points

f (x) = - 7 x^{3} + 21 x + 5

extreme f(x)=0.001x^2+2.4x-90 extreme points

f (x) = 0.001 x^{2} + 2.4 x - 90

extreme f(x,y)=8x^3-5x^2y+3xy^2 extreme points

f (x, y) = 8 x^{3} - 5 x^{2} y + 3 x y^{2}
