extreme x^2(2-x)^3

extreme points

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

Minimum (0, 0), Maximum (\frac{4}{5}, \frac{3456}{3125}), Saddle (2, 0)

Solution steps

f^{'} (x) = - x (x - 2)^{2} (5 x - 4)

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < \frac{4}{5},

Decreasing

: \frac{4}{5} < x < 2,

Decreasing

: 2 < x < \infty

Plug

x = 0

into

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

Minimum (0, 0)

Plug

x = \frac{4}{5}

into

x^{2} (2 - x)^{3} : \frac{3456}{3125}

Maximum (\frac{4}{5}, \frac{3456}{3125})

Plug

x = 2

into

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

Saddle (2, 0)

Minimum (0, 0), Maximum (\frac{4}{5}, \frac{3456}{3125}), Saddle (2, 0)

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

f (x, y) = (x + y)

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

cos (4 x)

f (x) = (x - 4)^{3}
