extreme-x^2+8x-9

Solution

extreme points

- x^{2} + 8 x - 9

Solution

Maximum (4, 7)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 4,

Decreasing

: 4 < x < \infty

Plug

x = 4

into

- x^{2} + 8 x - 9 : 7

Maximum (4, 7)

Popular Examples

extreme f(x)=x^3-12x^2-27x+2,1<= x<= 10 extreme points

f (x) = x^{3} - 12 x^{2} - 27 x + 2, 1 \leq x \leq 10

extreme 85y^{35}extreme points

85 y^{35}

extreme 2x^3+9x^2-24x extreme points

2 x^{3} + 9 x^{2} - 24 x

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

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

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

f (x) = x^{3} - x^{2} - x - 5
