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

Solution

extreme points

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

Solution

Minimum (\frac{5}{2}, - \frac{9}{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 + 4 : - \frac{9}{4}

Minimum (\frac{5}{2}, - \frac{9}{4})

Popular Examples

extreme f(y)=-0.06x^2-0.02y^2-1.5xy-85x+69y extreme points

f (y) = - 0.06 x^{2} - 0.02 y^{2} - 1.5 x y - 85 x + 69 y

extreme f(x)=3x+5 extreme points

f (x) = 3 x + 5

extreme p(t)=500e^{kt}extreme points

p (t) = 500 e^{k t}

extreme f(x)=400x^2-1600x^3,0<= x<= 0.25 extreme points

f (x) = 400 x^{2} - 1600 x^{3}, 0 \leq x \leq 0.25

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

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