- x^{4} + 2 x^{3}

Solution

(0, 0), (1, 1)

Solution steps

f^{''} (x) = - 12 x^{2} + 12 x

Find intervals:

Concave Downward

: - \infty < x < 0,

Concave Upward

: 0 < x < 1,

Concave Downward

: 1 < x < \infty

Plug

x = 0

into

- x^{4} + 2 x^{3} : 0

(0, 0)

Plug

x = 1

into

- x^{4} + 2 x^{3} : 1
