inflection x^3+2x^2+x-7

Solution

inflection points

x^{3} + 2 x^{2} + x - 7

Solution

(- \frac{2}{3}, - \frac{191}{27})

Solution steps

f^{''} (x) = 6 x + 4

Find intervals:

Concave Downward

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

Concave Upward

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

Plug

x = - \frac{2}{3}

into

x^{3} + 2 x^{2} + x - 7 : - \frac{191}{27}

(- \frac{2}{3}, - \frac{191}{27})

Popular Examples

inverse of f(x)= 1/5 x-2 inverse

f (x) = \frac{1}{5} x - 2

domain of f(x)=5x^2-2x+2 domain

f (x) = 5 x^{2} - 2 x + 2

asymptotes of 1/(x+3)asymptotes

\frac{1}{x + 3}

slope of-4/3 9 slope

- \frac{4}{3} 9

asymptotes of (x-9)/(sqrt(4x^2+3x+2))asymptotes

\frac{x - 9}{4 x ^{2} + 3 x + 2}
