extreme x^2+8x-9

Solution

extreme points

x^{2} + 8 x - 9

Solution

Minimum (- 4, - 25)

Solution steps

f^{'} (x) = 2 x + 8

Find intervals:

Decreasing

: - \infty < x < - 4,

Increasing

: - 4 < x < \infty

Plug

x = - 4

into

x^{2} + 8 x - 9 : - 25

Minimum (- 4, - 25)

Popular Examples

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

extreme 5xln(x)extreme points

5 x ln (x)

extreme f(x)=2e^{-x}(x^2-x+1)extreme points

f (x) = 2 e^{- x} (x^{2} - x + 1)

extreme x/(x^2-49)extreme points

\frac{x}{x ^{2} - 49}

extreme (3+x)/(x-2)extreme points

\frac{3 + x}{x - 2}
