inflection f(x)=2x^3-9x^2+27

Solution

inflection points

f (x) = 2 x^{3} - 9 x^{2} + 27

Solution

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

Solution steps

f^{''} (x) = 12 x - 18

Find intervals:

Concave Downward

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

Concave Upward

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

Plug

x = \frac{3}{2}

into

2 x^{3} - 9 x^{2} + 27 : \frac{27}{2}

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