extreme f(x)=7x^2+x-3

Solution

extreme points

f (x) = 7 x^{2} + x - 3

Solution

Minimum (- \frac{1}{14}, - \frac{85}{28})

Solution steps

f^{'} (x) = 14 x + 1

Find intervals:

Decreasing

: - \infty < x < - \frac{1}{14},

Increasing

: - \frac{1}{14} < x < \infty

Plug

x = - \frac{1}{14}

into

7 x^{2} + x - 3 : - \frac{85}{28}

Minimum (- \frac{1}{14}, - \frac{85}{28})

Popular Examples

extreme y=5x+(180)/x extreme points

y = 5 x + \frac{180}{x}

extreme (-8x^3+5x^2-1)/(2x^2-9x)extreme points

\frac{- 8 x ^{3} + 5 x ^{2} - 1}{2 x ^{2} - 9 x}

extreme f(x)=x-6sqrt(x+9)extreme points

f (x) = x - 6 x + 9

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

f (x) = \frac{x}{4 x - x ^{3}}

extreme x^2-10x-9,2<= x<= 7 extreme points

x^{2} - 10 x - 9, 2 \leq x \leq 7
