extreme (x^2+10)(9-x^2)

Solution

extreme points

(x^{2} + 10) (9 - x^{2})

Solution

Maximum (0, 90)

Solution steps

f^{'} (x) = - 2 x (2 x^{2} + 1)

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

(x^{2} + 10) (9 - x^{2}) : 90

Maximum (0, 90)

Popular Examples

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

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

extreme f(x)= 1/5 x^5-1/4 x^4-2x^3 extreme points

f (x) = \frac{1}{5} x^{5} - \frac{1}{4} x^{4} - 2 x^{3}

extreme f(x)=x^3-12x^2+48x-2 extreme points

f (x) = x^{3} - 12 x^{2} + 48 x - 2

extreme f(x)= 1/2 y^4-4xy+2x^4 extreme points

f (x) = \frac{1}{2} y^{4} - 4 x y + 2 x^{4}

extreme 30x-28ln(x)extreme points

30 x - 28 ln (x)
