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

Solution

inflection points

f (x) = x^{3} + 3 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} + 3 x + 9 : 9

(0, 9)

Popular Examples

parity f(x)=(5x)/(x^3-2x)parity

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

inverse of f(x)=log_{e}(x^2-1)inverse

f (x) = lo g_{e} (x^{2} - 1)

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

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

symmetry y=5x^2+6x+9 symmetry

y = 5 x^{2} + 6 x + 9

inverse of 6e^{x+1}-3 inverse

6 e^{x + 1} - 3
