extreme x^2-2x-18

Solution

extreme points

x^{2} - 2 x - 18

Solution

Minimum (1, - 19)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 1

into

x^{2} - 2 x - 18 : - 19

Minimum (1, - 19)

Popular Examples

extreme F(x,y)=200x+150y extreme points

F (x, y) = 200 x + 150 y

extreme f(x)=|x+1|extreme points

f (x) = ∣ x + 1 ∣

extreme 1/(sqrt(2pi))e^{-(x^2)/2}extreme points

\frac{1}{2 π} e^{- \frac{x ^{2}}{2}}

extreme-x^4+x^3+2x^2+11,0<= x<= 2 extreme points

- x^{4} + x^{3} + 2 x^{2} + 11, 0 \leq x \leq 2

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

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