extreme y=2x^3-6x+3

Solution

extreme points

y = 2 x^{3} - 6 x + 3

Solution

Maximum (- 1, 7), Minimum (1, - 1)

Solution steps

f^{'} (x) = 6 x^{2} - 6

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - 1

into

2 x^{3} - 6 x + 3 : 7

Maximum (- 1, 7)

Plug

x = 1

into

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

Minimum (1, - 1)

Maximum (- 1, 7), Minimum (1, - 1)

extreme f(x)=1-x^{2/3}extreme points

f (x) = 1 - x^{\frac{2}{3}}

extreme f(x)=12x+y-14 extreme points

f (x) = 12 x + y - 14

extreme f(x)=-2x^3+36x^2-120x+11 extreme points

f (x) = - 2 x^{3} + 36 x^{2} - 120 x + 11

extreme f(x)=8+5x-5x^2 extreme points

f (x) = 8 + 5 x - 5 x^{2}

extreme f(x)=x(23-48+2x)(48/2-x)extreme points

f (x) = x (23 - 48 + 2 x) (\frac{48}{2} - x)
