inflection f(x)=-4x^3-12x^2+8

Solution

inflection points

f (x) = - 4 x^{3} - 12 x^{2} + 8

Solution

(- 1, 0)

Solution steps

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

Find intervals:

Concave Upward

: - \infty < x < - 1,

Concave Downward

: - 1 < x < \infty

Plug

x = - 1

into

- 4 x^{3} - 12 x^{2} + 8 : 0

(- 1, 0)

Popular Examples

parity (sin(u^2))/(sin(u))parity

\frac{sin ( u ^{2} )}{sin ( u )}

range of (3-x^2)/2 range

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

inverse of f(x)=c(n)=50+4n inverse

f (x) = c (n) = 50 + 4 n

asymptotes of (5x^2+1)/(3x-2)asymptotes

\frac{5 x ^{2} + 1}{3 x - 2}

range of f(x)= x/(x^2+x-6)range

f (x) = \frac{x}{x ^{2} + x - 6}
