extreme x^2-x-1

Solution

extreme points

x^{2} - x - 1

Solution

Minimum (\frac{1}{2}, - \frac{5}{4})

Solution steps

f^{'} (x) = 2 x - 1

Find intervals:

Decreasing

: - \infty < x < \frac{1}{2},

Increasing

: \frac{1}{2} < x < \infty

Plug

x = \frac{1}{2}

into

x^{2} - x - 1 : - \frac{5}{4}

Minimum (\frac{1}{2}, - \frac{5}{4})

Popular Examples

extreme f(x)=6x^4-4x^6 extreme points

f (x) = 6 x^{4} - 4 x^{6}

extreme f(x)=-x^4+x^3+19 extreme points

f (x) = - x^{4} + x^{3} + 19

extreme f(x)=(x+3)/(x-3)extreme points

f (x) = \frac{x + 3}{x - 3}

extreme f(x,y)=-3x^2+5xy-2y^2+x+y extreme points

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

extreme f(x,y)=ye^{x^2}extreme points

f (x, y) = y e^{x^{2}}
