inflection f(x)=-x^3+9x^2-8x-4

Solution

inflection points

f (x) = - x^{3} + 9 x^{2} - 8 x - 4

Solution

(3, 26)

Solution steps

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

Find intervals:

Concave Upward

: - \infty < x < 3,

Concave Downward

: 3 < x < \infty

Plug

x = 3

into

- x^{3} + 9 x^{2} - 8 x - 4 : 26

(3, 26)

Popular Examples

critical (x-3)^{2/3}critical points

(x - 3)^{\frac{2}{3}}

frequency 4sin(6/7 x)+5 frequency

4 sin (\frac{6}{7} x) + 5

parity f(x)= 5/x parity

f (x) = \frac{5}{x}

domain of f(x)=sqrt(3x-x^2)domain

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

inverse of f(x)=log_{6}(x-2)inverse

f (x) = lo g_{6} (x - 2)
