extreme f(x)=-x^2+4x

Solution

extreme points

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

Solution

Maximum (2, 4)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 2,

Decreasing

: 2 < x < \infty

Plug

x = 2

into

- x^{2} + 4 x : 4

Maximum (2, 4)

Popular Examples

extreme f(x)=(x+1)/(x-1)extreme points

f (x) = \frac{x + 1}{x - 1}

extreme f(x)=e^x(24-x^2)extreme points

f (x) = e^{x} (24 - x^{2})

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

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

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

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

extreme x^2-2x extreme points

x^{2} - 2 x
