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

Solution

extreme points

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

Solution

Minimum (\frac{2}{3}, - \frac{7}{3})

Solution steps

f^{'} (x) = 6 x - 4

Find intervals:

Decreasing

: - \infty < x < \frac{2}{3},

Increasing

: \frac{2}{3} < x < \infty

Plug

x = \frac{2}{3}

into

3 x^{2} - 4 x - 1 : - \frac{7}{3}

Minimum (\frac{2}{3}, - \frac{7}{3})
