extreme-x^3+12x-19

Solution

extreme points

- x^{3} + 12 x - 19

Solution

Minimum (- 2, - 35), Maximum (2, - 3)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < 2,

Decreasing

: 2 < x < \infty

Plug

x = - 2

into

- x^{3} + 12 x - 19 : - 35

Minimum (- 2, - 35)

Plug

x = 2

into

- x^{3} + 12 x - 19 : - 3

Maximum (2, - 3)

Minimum (- 2, - 35), Maximum (2, - 3)

Popular Examples

extreme f(x)=68-x^2-y^2 extreme points

f (x) = 68 - x^{2} - y^{2}

extreme y=(x^2)/(x^2+243)extreme points

y = \frac{x ^{2}}{x ^{2} + 243}

extreme f(x,y)=ln(2x^2+y^2-1)extreme points

f (x, y) = ln (2 x^{2} + y^{2} - 1)

extreme f(x)=2x^2-8xy+10y^2+10x-4y-5 extreme points

f (x) = 2 x^{2} - 8 x y + 10 y^{2} + 10 x - 4 y - 5

extreme f(x)=2x^4-8x^3+4 extreme points

f (x) = 2 x^{4} - 8 x^{3} + 4
