extreme 3(x-2)^2(x-1)+(x-2)^2

extreme points

3 (x - 2)^{2} (x - 1) + (x - 2)^{2}

Maximum (\frac{10}{9}, \frac{256}{243}), Minimum (2, 0)

Solution steps

f^{'} (x) = 9 x^{2} - 28 x + 20

Find intervals:

Increasing

: - \infty < x < \frac{10}{9},

Decreasing

: \frac{10}{9} < x < 2,

Increasing

: 2 < x < \infty

Plug

x = \frac{10}{9}

into

3 (x - 2)^{2} (x - 1) + (x - 2)^{2} : \frac{256}{243}

Maximum (\frac{10}{9}, \frac{256}{243})

Plug

x = 2

into

3 (x - 2)^{2} (x - 1) + (x - 2)^{2} : 0

Minimum (2, 0)

Maximum (\frac{10}{9}, \frac{256}{243}), Minimum (2, 0)

f (x, y) = \frac{3 x - y}{4}

\frac{x ^{3} + 8}{x}

P (x, y) = 2 x + 3 y

e^{x y}

x 49 - x^{2}
