inflection x^3-27x+9

Solution

inflection points

x^{3} - 27 x + 9

Solution

(0, 9)

Solution steps

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

Find intervals:

Concave Downward

: - \infty < x < 0,

Concave Upward

: 0 < x < \infty

Plug

x = 0

into

x^{3} - 27 x + 9 : 9

(0, 9)

Popular Examples

perpendicular 5y-4x=-15 perpendicular

5 y - 4 x = - 15

intercepts of f(x)=2x^3-4x^2 intercepts

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

inverse of f(x)=(-5x+2)/(6x+3)inverse

f (x) = \frac{- 5 x + 2}{6 x + 3}

range of f(x)=-4sqrt(5-2x)range

f (x) = - 4 5 - 2 x

inverse of 3/(2-7x)inverse

\frac{3}{2 - 7 x}
