inflection f(x)=x^2(3-x)^2

inflection points

f (x) = x^{2} (3 - x)^{2}

(\frac{3 - 3}{2}, \frac{9}{4}), (\frac{3 + 3}{2}, \frac{9}{4})

Solution steps

f^{''} (x) = 2 (6 x^{2} - 18 x + 9)

Find intervals:

Concave Upward

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

Concave Downward

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

Concave Upward

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

Plug

x = \frac{3 - 3}{2}

into

x^{2} (3 - x)^{2} : \frac{9}{4}

(\frac{3 - 3}{2}, \frac{9}{4})

Plug

x = \frac{3 + 3}{2}

into

x^{2} (3 - x)^{2} : \frac{9}{4}

(\frac{3 + 3}{2}, \frac{9}{4})

(\frac{3 - 3}{2}, \frac{9}{4}), (\frac{3 + 3}{2}, \frac{9}{4})

f (x) = x^{2} + 6 x + 8

y = 2 x^{2} - 16

f (x) = \frac{x - 2}{x + 5}

f (x) = \frac{99}{x ( x + 11 )}

f (x) = lo g_{3} (x - 4)
