extreme f(x)=2+8x-x^2

Solution

extreme points

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

Solution

Maximum (4, 18)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 4,

Decreasing

: 4 < x < \infty

Plug

x = 4

into

2 + 8 x - x^{2} : 18

Maximum (4, 18)

Popular Examples

extreme f(x,y)=5x^4-x^2+6y^2 extreme points

f (x, y) = 5 x^{4} - x^{2} + 6 y^{2}

extreme f(x)=8-2x^2 extreme points

f (x) = 8 - 2 x^{2}

extreme f(x)= 2/(x+7)extreme points

f (x) = \frac{2}{x + 7}

extreme f(x)=(x-2)^5 extreme points

f (x) = (x - 2)^{5}

extreme f(x)=-16-7x-x^2 extreme points

f (x) = - 16 - 7 x - x^{2}
