extreme f(x)=x^2-4x+9

Solution

extreme points

f (x) = x^{2} - 4 x + 9

Solution

Minimum (2, 5)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 2,

Increasing

: 2 < x < \infty

Plug

x = 2

into

x^{2} - 4 x + 9 : 5

Minimum (2, 5)

Popular Examples

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

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

extreme 1-e^{-0.5x}extreme points

1 - e^{- 0.5 x}

extreme f(x,y)=2xy+1/x+4/y extreme points

f (x, y) = 2 x y + \frac{1}{x} + \frac{4}{y}

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

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

extreme f(x)=sqrt(x)ln(8x)extreme points

f (x) = x ln (8 x)
