extreme y=x^2+4x-7

Solution

extreme points

y = 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)= 4/3 x^{3/2}-1/2 x^2 extreme points

f (x) = \frac{4}{3} x^{\frac{3}{2}} - \frac{1}{2} x^{2}

extreme y=(x^2-9)^3 extreme points

y = (x^{2} - 9)^{3}

extreme f(x)= 1/x ,[1,infinity ]extreme points

f (x) = \frac{1}{x}, [1, \infty]

extreme f(x)=-0.1x^2+1.4x+98.9 extreme points

f (x) = - 0.1 x^{2} + 1.4 x + 98.9

extreme f(x,y)=6y^2+4x^2+4xy-16y+8x extreme points

f (x, y) = 6 y^{2} + 4 x^{2} + 4 x y - 16 y + 8 x
