extreme f(x)=-9x^2+126x-45

Solution

extreme points

f (x) = - 9 x^{2} + 126 x - 45

Solution

Maximum (7, 396)

Solution steps

f^{'} (x) = - 18 x + 126

Find intervals:

Increasing

: - \infty < x < 7,

Decreasing

: 7 < x < \infty

Plug

x = 7

into

- 9 x^{2} + 126 x - 45 : 396

Maximum (7, 396)

Popular Examples

3 x^{2} ln (x)

extreme f(x,y)=6xy-x^3-3y^2 extreme points

f (x, y) = 6 x y - x^{3} - 3 y^{2}

extreme f(x)=8y^2+5x^2-10y+6x-10 extreme points

f (x) = 8 y^{2} + 5 x^{2} - 10 y + 6 x - 10

extreme f(x)=2x^3-3x^2-12x-1 extreme points

f (x) = 2 x^{3} - 3 x^{2} - 12 x - 1

extreme f(x,y)=x^3+y^2+3/2 x^2-6x-4y+3 extreme points

f (x, y) = x^{3} + y^{2} + \frac{3}{2} x^{2} - 6 x - 4 y + 3
