inflection 1-9x-6x^2-x^3

Solution

inflection points

1 - 9 x - 6 x^{2} - x^{3}

Solution

(- 2, 3)

Solution steps

f^{''} (x) = - 6 x - 12

Find intervals:

Concave Upward

: - \infty < x < - 2,

Concave Downward

: - 2 < x < \infty

Plug

x = - 2

into

1 - 9 x - 6 x^{2} - x^{3} : 3

(- 2, 3)

Popular Examples

domain of sqrt(x)+11 domain

x + 11

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

f (x) = \frac{4}{( x - 2 ) ^{2}}

parity f(x)=x^4-2x parity

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

distance (6,0),(1,-3)distance

(6, 0), (1, - 3)

frequency 8cos(pi(x-1/10))frequency

8 cos (π (x - \frac{1}{10}))
