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

Solution

extreme points

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

Solution

Maximum (1, 5)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = 1

into

2 + 4 x - x^{4} : 5

Maximum (1, 5)

Popular Examples

extreme f(x,y)=5x+6y extreme points

f (x, y) = 5 x + 6 y

extreme x^2+6xy+2y^2 extreme points

x^{2} + 6 x y + 2 y^{2}

extreme+(x+1/x+8)/(x+1/x+2)extreme points

+ \frac{x + \frac{1}{x} + 8}{x + \frac{1}{x} + 2}

extreme f(x,y)=6(1-x^{(2)})*(1-y^{(2)})extreme points

f (x, y) = 6 (1 - x^{(2)}) \cdot (1 - y^{(2)})

extreme f(x)=-2x^2ln(x)+17x^2 extreme points

f (x) = - 2 x^{2} ln (x) + 17 x^{2}
