extreme 2x^2-9x-1

Solution

extreme points

2 x^{2} - 9 x - 1

Solution

Minimum (\frac{9}{4}, - \frac{89}{8})

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < \frac{9}{4},

Increasing

: \frac{9}{4} < x < \infty

Plug

x = \frac{9}{4}

into

2 x^{2} - 9 x - 1 : - \frac{89}{8}

Minimum (\frac{9}{4}, - \frac{89}{8})

Popular Examples

extreme f(x)=x+(16)/x ,4<= x<= 25 extreme points

f (x) = x + \frac{16}{x}, 4 \leq x \leq 25

extreme f(x)=60x^3-120x extreme points

f (x) = 60 x^{3} - 120 x

extreme 2y extreme points

2 y

extreme f(x,y)=xy^2-x+1 extreme points

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

extreme f(x)= 5/3 x^3(-65)/2 x^2+200x-1 extreme points

f (x) = \frac{5}{3} x^{3} \frac{- 65}{2} x^{2} + 200 x - 1
