extreme x^2+4x-1

Solution

extreme points

x^{2} + 4 x - 1

Solution

Minimum (- 2, - 5)

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 - 1 : - 5

Minimum (- 2, - 5)

Popular Examples

extreme f(x)=2x^3-6x+3,-2<= x<= 2 extreme points

f (x) = 2 x^{3} - 6 x + 3, - 2 \leq x \leq 2

extreme f(x)=-20x^5-5x^4+x^2-17 extreme points

f (x) = - 20 x^{5} - 5 x^{4} + x^{2} - 17

extreme f(x)=2x^3+3x^2-12x+8,-2<= x<= 4 extreme points

f (x) = 2 x^{3} + 3 x^{2} - 12 x + 8, - 2 \leq x \leq 4

extreme f(x)=2x^3-3x^2-12+1,-2<= x<= 3 extreme points

f (x) = 2 x^{3} - 3 x^{2} - 12 + 1, - 2 \leq x \leq 3
