extreme f(x)=-2x^2+8x+13

Solution

extreme points

f (x) = - 2 x^{2} + 8 x + 13

Solution

Maximum (2, 21)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 2,

Decreasing

: 2 < x < \infty

Plug

x = 2

into

- 2 x^{2} + 8 x + 13 : 21

Maximum (2, 21)

Popular Examples

extreme f(x)=x^3-27x^2+216x extreme points

f (x) = x^{3} - 27 x^{2} + 216 x

extreme f(x)=(9x^2-1)(1+4y)extreme points

f (x) = (9 x^{2} - 1) (1 + 4 y)

extreme f(x)=2x^3+6x-9 extreme points

f (x) = 2 x^{3} + 6 x - 9
