extreme f(x)=x^2-4x-7

Solution

extreme points

f (x) = x^{2} - 4 x - 7

Solution

Minimum (2, - 11)

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 - 7 : - 11

Minimum (2, - 11)

Popular Examples

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

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

extreme f(x)=5x+4y extreme points

f (x) = 5 x + 4 y

extreme x^4-242x^2-2 extreme points

x^{4} - 242 x^{2} - 2

extreme f(x)=x(20-2x)(32-2x),0<x<10 extreme points

f (x) = x (20 - 2 x) (32 - 2 x), 0 < x < 10

extreme f(x)=3|x-1|,0<x<3 extreme points

f (x) = 3 ∣ x - 1 ∣, 0 < x < 3
