inflection f(x)=3x^3-9x

Solution

inflection points

f (x) = 3 x^{3} - 9 x

Solution

(0, 0)

Solution steps

f^{''} (x) = 18 x

Find intervals:

Concave Downward

: - \infty < x < 0,

Concave Upward

: 0 < x < \infty

Plug

x = 0

into

3 x^{3} - 9 x : 0

(0, 0)

Popular Examples

domain of (20x+99)/(x(x+11))domain

\frac{20 x + 99}{x ( x + 11 )}

inverse of f(x)=-4/x inverse

f (x) = - \frac{4}{x}

inverse of f(x)=3(x-2)^2+4 inverse

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

symmetry x^5+5y^3=2y symmetry

x^{5} + 5 y^{3} = 2 y

inverse of f(x)=x^2+10 inverse

f (x) = x^{2} + 10
