extreme f(x)=x^4-4x+7

Solution

extreme points

f (x) = x^{4} - 4 x + 7

Solution

Minimum (1, 4)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 1

into

x^{4} - 4 x + 7 : 4

Minimum (1, 4)

Popular Examples

extreme f(x)=400-(3600)/(x+8)-x extreme points

f (x) = 400 - \frac{3600}{x + 8} - x

extreme f(x)=3x^2-2x^2-5x+6 extreme points

f (x) = 3 x^{2} - 2 x^{2} - 5 x + 6

extreme f(x)=In(x+sqrt(1+x^2))extreme points

f (x) = I n (x + 1 + x^{2})

extreme f(x)=x^4-4x-8 extreme points

f (x) = x^{4} - 4 x - 8

extreme f(x)=-2x^3+83x^2+212 extreme points

f (x) = - 2 x^{3} + 83 x^{2} + 212
