extreme f(x)=x^2-18x+86

Solution

extreme points

f (x) = x^{2} - 18 x + 86

Solution

Minimum (9, 5)

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 + 86 : 5

Minimum (9, 5)

extreme (-3)/(x-4)extreme points

\frac{- 3}{x - 4}

extreme f(x,y)=x^3+y^3+12xy+5 extreme points

f (x, y) = x^{3} + y^{3} + 12 x y + 5

extreme ln(x+y)-ln(1+xy)extreme points

ln (x + y) - ln (1 + x y)

extreme f(x)= x/(\sqrt[3]{x^2-2)}extreme points

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