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

Solution

extreme points

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

Solution

Maximum (1, 2)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = 1

into

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

Maximum (1, 2)

Popular Examples

extreme g(x)=x^3-3x^2+1 extreme points

g (x) = x^{3} - 3 x^{2} + 1

extreme f(x)=((x-1)^2)/x extreme points

f (x) = \frac{( x - 1 ) ^{2}}{x}

extreme f(x,y)=4xy+2/x+1/y extreme points

f (x, y) = 4 x y + \frac{2}{x} + \frac{1}{y}

extreme f(x)=x^4-8x^3+6 extreme points

f (x) = x^{4} - 8 x^{3} + 6

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

f (x) = \frac{x ^{3}}{3 - x ^{2}}
