inflection f(x)=-5x^3-30x^2

Solution

inflection points

f (x) = - 5 x^{3} - 30 x^{2}

Solution

(- 2, - 80)

Solution steps

f^{''} (x) = - 30 x - 60

Find intervals:

Concave Upward

: - \infty < x < - 2,

Concave Downward

: - 2 < x < \infty

Plug

x = - 2

into

- 5 x^{3} - 30 x^{2} : - 80

(- 2, - 80)

Popular Examples

range of f(x)=3-x range

f (x) = 3 - x

range of f(x)=x^2+8x+15 range

f (x) = x^{2} + 8 x + 15

amplitude of-cos(2(θ-pi/4))amplitude

- cos (2 (θ - \frac{π}{4}))

critical f(x)=3x^5-20x^3 critical points

f (x) = 3 x^{5} - 20 x^{3}

domain of f(x)=(8-x)/(x^2-7x)domain

f (x) = \frac{8 - x}{x ^{2} - 7 x}
