extreme f(x)=-x^2+10x-21

Solution

extreme points

f (x) = - x^{2} + 10 x - 21

Solution

Maximum (5, 4)

Solution steps

f^{'} (x) = - 2 x + 10

Find intervals:

Increasing

: - \infty < x < 5,

Decreasing

: 5 < x < \infty

Plug

x = 5

into

- x^{2} + 10 x - 21 : 4

Maximum (5, 4)

Popular Examples

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

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

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

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

extreme f(x,y)= x/(x^2+y^2)extreme points

f (x, y) = \frac{x}{x ^{2} + y ^{2}}

extreme f(x,y)=xln(y^2-x)extreme points

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

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

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