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

Solution

extreme points

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

Solution

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

Solution steps

f^{'} (x) = 18 x - 4

Find intervals:

Decreasing

: - \infty < x < \frac{2}{9},

Increasing

: \frac{2}{9} < x < \infty

Plug

x = \frac{2}{9}

into

9 x^{2} - 4 x : - \frac{4}{9}

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

Popular Examples

extreme f(x)=-(x+1)^2*(x+3)^3*(x-4)^2 extreme points

f (x) = - (x + 1)^{2} \cdot (x + 3)^{3} \cdot (x - 4)^{2}

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

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

extreme f(x,y)=4x^2+2y^2+5 extreme points

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

extreme 1-|x|extreme points

1 - ∣ x ∣

extreme f(x)=-8x^3+24x+9 extreme points

f (x) = - 8 x^{3} + 24 x + 9
