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

Solution

extreme points

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

Solution

Minimum (\frac{1}{10}, - \frac{41}{20})

Solution steps

f^{'} (x) = 10 x - 1

Find intervals:

Decreasing

: - \infty < x < \frac{1}{10},

Increasing

: \frac{1}{10} < x < \infty

Plug

x = \frac{1}{10}

into

5 x^{2} - x - 2 : - \frac{41}{20}

Minimum (\frac{1}{10}, - \frac{41}{20})
