extreme f(x)=x^2-5x+1

Solution

extreme points

f (x) = x^{2} - 5 x + 1

Solution

Minimum (\frac{5}{2}, - \frac{21}{4})

Solution steps

f^{'} (x) = 2 x - 5

Find intervals:

Decreasing

: - \infty < x < \frac{5}{2},

Increasing

: \frac{5}{2} < x < \infty

Plug

x = \frac{5}{2}

into

x^{2} - 5 x + 1 : - \frac{21}{4}

Minimum (\frac{5}{2}, - \frac{21}{4})

Popular Examples

extreme f(x,y)=e^{4xy}+5y extreme points

f (x, y) = e^{4 x y} + 5 y

extreme f(x)= x/2-cos(x)extreme points

f (x) = \frac{x}{2} - cos (x)

extreme f(x)=-2(4x-5)e^{4x}extreme points

f (x) = - 2 (4 x - 5) e^{4 x}

extreme f(x)=(2cos(θ)+cos^2(θ))extreme points

f (x) = (2 cos (θ) + cos^{2} (θ))

extreme f(x,y)=2x^2-x^4+3y^2-y^3 extreme points

f (x, y) = 2 x^{2} - x^{4} + 3 y^{2} - y^{3}
