inflection y=x^3-15x^2+75x-1

Solution

inflection points

y = x^{3} - 15 x^{2} + 75 x - 1

Solution

(5, 124)

Solution steps

f^{''} (x) = 6 x - 30

Find intervals:

Concave Downward

: - \infty < x < 5,

Concave Upward

: 5 < x < \infty

Plug

x = 5

into

x^{3} - 15 x^{2} + 75 x - 1 : 124

(5, 124)

Popular Examples

periodicity of f(x)=3sin(2/3 x)periodicity

f (x) = 3 sin (\frac{2}{3} x)

intercepts of y=-2x-21 intercepts

y = - 2 x - 21

intercepts of y=-2x intercepts

y = - 2 x

domain of f(x)=4+sqrt(x-3)domain

f (x) = 4 + x - 3

extreme f(x)=x^3-2x^2-4x+5 extreme points

f (x) = x^{3} - 2 x^{2} - 4 x + 5
