inflection-x^4-9x^3+8x+5

inflection points

- x^{4} - 9 x^{3} + 8 x + 5

(- \frac{9}{2}, \frac{6065}{16}), (0, 5)

Solution steps

f^{''} (x) = - 12 x^{2} - 54 x

Find intervals:

Concave Downward

: - \infty < x < - \frac{9}{2},

Concave Upward

: - \frac{9}{2} < x < 0,

Concave Downward

: 0 < x < \infty

Plug

x = - \frac{9}{2}

into

- x^{4} - 9 x^{3} + 8 x + 5 : \frac{6065}{16}

(- \frac{9}{2}, \frac{6065}{16})

Plug

x = 0

into

- x^{4} - 9 x^{3} + 8 x + 5 : 5

(0, 5)

(- \frac{9}{2}, \frac{6065}{16}), (0, 5)

9 - x^{2}

y = \frac{x - 2}{- 2 x + 7}

f (x) = cos (3 x)

(0, - 3), (5, 0)

f (x) = \frac{( x ^{2} - 8 x + 15 )}{x - 5}
