extreme x^2-4x[-1.4]

Solution

extreme points

x^{2} - 4 x [- 1.4]

Solution

Minimum (- 2.8, - 7.84)

Solution steps

f^{'} (x) = 2 x + 5.6

Find intervals:

Decreasing

: - \infty < x < - 2.8,

Increasing

: - 2.8 < x < \infty

Plug

x = - 2.8

into

x^{2} - 4 x [- 1.4] : - 7.84

Minimum (- 2.8, - 7.84)

Popular Examples

extreme f(x)=-x^4+2x^2y-1/2 y^2-4y+12 extreme points

f (x) = - x^{4} + 2 x^{2} y - \frac{1}{2} y^{2} - 4 y + 12

extreme f(xy)=y^2ln(x^2y)extreme points

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

extreme f(x)=2x^4-8x extreme points

f (x) = 2 x^{4} - 8 x

extreme 4x^3-12x^2+8x extreme points

4 x^{3} - 12 x^{2} + 8 x

extreme f(x)=6x^2-6x-36 extreme points

f (x) = 6 x^{2} - 6 x - 36
