inflection x^3-18x^2+81x+13

Solution

inflection points

x^{3} - 18 x^{2} + 81 x + 13

Solution

(6, 67)

Solution steps

f^{''} (x) = 6 x - 36

Find intervals:

Concave Downward

: - \infty < x < 6,

Concave Upward

: 6 < x < \infty

Plug

x = 6

into

x^{3} - 18 x^{2} + 81 x + 13 : 67

(6, 67)

Popular Examples

extreme f(x)=\sqrt[3]{x+1}extreme points

inverse of f(x)=(2x)/((x-3))inverse

f (x) = \frac{2 x}{( x - 3 )}

range of f(x)=|x-3|range

f (x) = ∣ x - 3 ∣

extreme e^{-x}extreme points

e^{- x}

domain of f(x)=sqrt(1-\sqrt{1-x^2)}domain

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