inflection x^3-2x^2-4x

Solution

inflection points

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

Solution

(\frac{2}{3}, - \frac{88}{27})

Solution steps

f^{''} (x) = 6 x - 4

Find intervals:

Concave Downward

: - \infty < x < \frac{2}{3},

Concave Upward

: \frac{2}{3} < x < \infty

Plug

x = \frac{2}{3}

into

x^{3} - 2 x^{2} - 4 x : - \frac{88}{27}

(\frac{2}{3}, - \frac{88}{27})
