extreme f(x)=5x^2-2x-3

Solution

extreme points

f (x) = 5 x^{2} - 2 x - 3

Solution

Minimum (\frac{1}{5}, - \frac{16}{5})

Solution steps

f^{'} (x) = 10 x - 2

Find intervals:

Decreasing

: - \infty < x < \frac{1}{5},

Increasing

: \frac{1}{5} < x < \infty

Plug

x = \frac{1}{5}

into

5 x^{2} - 2 x - 3 : - \frac{16}{5}

Minimum (\frac{1}{5}, - \frac{16}{5})
