extreme f(x)=x^2+10x-21

Solution

extreme points

f (x) = x^{2} + 10 x - 21

Solution

Minimum (- 5, - 46)

Solution steps

f^{'} (x) = 2 x + 10

Find intervals:

Decreasing

: - \infty < x < - 5,

Increasing

: - 5 < x < \infty

Plug

x = - 5

into

x^{2} + 10 x - 21 : - 46

Minimum (- 5, - 46)

Popular Examples

extreme 1+1/x-1/(x^2)extreme points

1 + \frac{1}{x} - \frac{1}{x ^{2}}

extreme x^2+4x+3 extreme points

x^{2} + 4 x + 3

extreme f(x,y)=-7y^2-3x^2+15y+9x extreme points

f (x, y) = - 7 y^{2} - 3 x^{2} + 15 y + 9 x

extreme f(x,y)=(xy+x-y+2)/(x^2y+1)extreme points

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

extreme f(x,y)=x^{10}-y^{10}-10x+10y-1 extreme points

f (x, y) = x^{10} - y^{10} - 10 x + 10 y - 1
