inflection f(x)=2x^3-3x^2+8x-1

inflection points

f (x) = 2 x^{3} - 3 x^{2} + 8 x - 1

(\frac{1}{2}, \frac{5}{2})

Solution steps

f^{''} (x) = 12 x - 6

Find intervals:

Concave Downward

: - \infty < x < \frac{1}{2},

Concave Upward

: \frac{1}{2} < x < \infty

Plug

x = \frac{1}{2}

into

2 x^{3} - 3 x^{2} + 8 x - 1 : \frac{5}{2}

(\frac{1}{2}, \frac{5}{2})
