extreme f(x)= 1/2 x^2-9x+7

Solution

extreme points

f (x) = \frac{1}{2} x^{2} - 9 x + 7

Solution

Minimum (9, - \frac{67}{2})

Solution steps

f^{'} (x) = x - 9

Find intervals:

Decreasing

: - \infty < x < 9,

Increasing

: 9 < x < \infty

Plug

x = 9

into

\frac{1}{2} x^{2} - 9 x + 7 : - \frac{67}{2}

Minimum (9, - \frac{67}{2})

Popular Examples

extreme f(x)=-3x^2+10x-3 extreme points

f (x) = - 3 x^{2} + 10 x - 3

extreme f(x)=10-8x^2 extreme points

f (x) = 10 - 8 x^{2}

extreme f(x)=2x-(800)/(x^2)extreme points

f (x) = 2 x - \frac{800}{x ^{2}}

extreme f(x)=|-4x-5|,-5<x<1 extreme points

f (x) = ∣ - 4 x - 5 ∣, - 5 < x < 1

extreme f(x,y)=3x^6y-5xy^2 extreme points

f (x, y) = 3 x^{6} y - 5 x y^{2}
