inflection 4x^3-5x^2+2x-1

Solution

inflection points

4 x^{3} - 5 x^{2} + 2 x - 1

Solution

(\frac{5}{12}, - \frac{161}{216})

Solution steps

f^{''} (x) = 24 x - 10

Find intervals:

Concave Downward

: - \infty < x < \frac{5}{12},

Concave Upward

: \frac{5}{12} < x < \infty

Plug

x = \frac{5}{12}

into

4 x^{3} - 5 x^{2} + 2 x - 1 : - \frac{161}{216}

(\frac{5}{12}, - \frac{161}{216})
