extreme f(x)=x^4(x-1)^2

extreme

Minimum (0, 0), Maximum (\frac{2}{3}, \frac{16}{729}), Minimum (1, 0)

Solution steps

f^{'} (x) = 2 x^{3} (x - 1) (3 x - 2)

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < \frac{2}{3},

Decreasing

: \frac{2}{3} < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 0

into

x^{4} (x - 1)^{2} : 0

Minimum (0, 0)

Plug

x = \frac{2}{3}

into

x^{4} (x - 1)^{2} : \frac{16}{729}

Maximum (\frac{2}{3}, \frac{16}{729})

Plug

x = 1

into

x^{4} (x - 1)^{2} : 0

Minimum (1, 0)

Minimum (0, 0), Maximum (\frac{2}{3}, \frac{16}{729}), Minimum (1, 0)
