inflection 6x^5-10x^3

inflection points

6 x^{5} - 10 x^{3}

(- \frac{1}{2}, \frac{7}{2 2}), (0, 0), (\frac{1}{2}, - \frac{7}{2 2})

Solution steps

f^{''} (x) = 120 x^{3} - 60 x

Find intervals:

Concave Downward

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

Concave Upward

: - \frac{1}{2} < x < 0,

Concave Downward

: 0 < x < \frac{1}{2},

Concave Upward

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

Plug

x = - \frac{1}{2}

into

6 x^{5} - 10 x^{3} : \frac{7}{2 2}

(- \frac{1}{2}, \frac{7}{2 2})

Plug

x = 0

into

6 x^{5} - 10 x^{3} : 0

(0, 0)

Plug

x = \frac{1}{2}

into

6 x^{5} - 10 x^{3} : - \frac{7}{2 2}

(\frac{1}{2}, - \frac{7}{2 2})

(- \frac{1}{2}, \frac{7}{2 2}), (0, 0), (\frac{1}{2}, - \frac{7}{2 2})

14

f (x) = \frac{4}{( x - 2 ) ^{2}}

f (x) = 2 x \cdot arctan (\frac{1}{x})

y = 3 x^{2} - 12 x + 11

e^{x + 2} - 3
