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

Solution

extreme points

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

Solution

Minimum (2, - 4)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 2,

Increasing

: 2 < x < \infty

Plug

x = 2

into

x^{2} - 4 x : - 4

Minimum (2, - 4)

Popular Examples

domain of f(x)=5x-1 domain

f (x) = 5 x - 1

inverse of f(x)=(2x-1)/(2x+9)inverse

f (x) = \frac{2 x - 1}{2 x + 9}

asymptotes of f(x)=(x+7)/(x^2+2x-3)asymptotes

f (x) = \frac{x + 7}{x ^{2} + 2 x - 3}

domain of f(x)=(3-x^2)/(x^2-4)domain

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

intercepts of 2y=-7 intercepts

2 y = - 7
