extreme f(x)=-3x^2+30x-4

Solution

extreme points

f (x) = - 3 x^{2} + 30 x - 4

Solution

Maximum (5, 71)

Solution steps

f^{'} (x) = - 6 x + 30

Find intervals:

Increasing

: - \infty < x < 5,

Decreasing

: 5 < x < \infty

Plug

x = 5

into

- 3 x^{2} + 30 x - 4 : 71

Maximum (5, 71)

extreme F(x,y)=y^2-x^2 extreme points

F (x, y) = y^{2} - x^{2}

extreme f(x,y)=-6x^2-3xy-3y^2-69x-9y+7 extreme points

f (x, y) = - 6 x^{2} - 3 x y - 3 y^{2} - 69 x - 9 y + 7

extreme x^3-3x-2 extreme points

x^{3} - 3 x - 2
