extreme f(x)=x^2-18x

Solution

extreme points

f (x) = x^{2} - 18 x

Solution

Minimum (9, - 81)

Solution steps

f^{'} (x) = 2 x - 18

Find intervals:

Decreasing

: - \infty < x < 9,

Increasing

: 9 < x < \infty

Plug

x = 9

into

x^{2} - 18 x : - 81

Minimum (9, - 81)

Popular Examples

extreme f(x,y)=sqrt(400-49x^2-16y^2)extreme points

f (x, y) = 400 - 49 x^{2} - 16 y^{2}

extreme f(x)=(3x)/(x^2+1),-4<= x<= 4 extreme points

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

extreme f(x)=x^3+y^3-3x^2-6y^2-9x extreme points

f (x) = x^{3} + y^{3} - 3 x^{2} - 6 y^{2} - 9 x

extreme 2x^3-x^2-4x+12 extreme points

2 x^{3} - x^{2} - 4 x + 12

extreme f(x)=x^3-3/2 x^2-6x+1 extreme points

f (x) = x^{3} - \frac{3}{2} x^{2} - 6 x + 1
