inflection 1/3 x^3+x^2-3x-5

Solution

inflection points

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

Solution

(- 1, - \frac{4}{3})

Solution steps

f^{''} (x) = 2 x + 2

Find intervals:

Concave Downward

: - \infty < x < - 1,

Concave Upward

: - 1 < x < \infty

Plug

x = - 1

into

\frac{1}{3} x^{3} + x^{2} - 3 x - 5 : - \frac{4}{3}

(- 1, - \frac{4}{3})

Popular Examples

domain of f(x)=x-1/x domain

f (x) = x - \frac{1}{x}

extreme f(x)=x^2(x-2)^2(x-1)^2 extreme points

f (x) = x^{2} (x - 2)^{2} (x - 1)^{2}

asymptotes of f(x)=((x^2+1))/(x^3+1)asymptotes

f (x) = \frac{( x ^{2} + 1 )}{x ^{3} + 1}

inverse of f(x)= 1/27 x^3 inverse

f (x) = \frac{1}{27} x^{3}

domain of f(x)=sqrt(x^2-2x-8)domain

f (x) = x^{2} - 2 x - 8
