extreme f(x)=5x^3-4

Solution

extreme points

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

Solution

Saddle (0, - 4)

Solution steps

f^{'} (x) = 15 x^{2}

Find intervals:

Increasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug

x = 0

into

5 x^{3} - 4 : - 4

Saddle (0, - 4)

Popular Examples

extreme f(x)=-x-(144)/x [9.13]extreme points

f (x) = - x - \frac{144}{x} [9.13]

extreme f(x)=-x^3+12x-24 extreme points

f (x) = - x^{3} + 12 x - 24

extreme f(x)=x^2-4x+16 extreme points

f (x) = x^{2} - 4 x + 16

extreme f(x)=-x^3+12x-15 extreme points

f (x) = - x^{3} + 12 x - 15

extreme y=-4x^3-18x^2+216x-12 extreme points

y = - 4 x^{3} - 18 x^{2} + 216 x - 12
