extreme f(x)=4x^2+3x^2-6x+1

extreme

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

Solution steps

f^{'} (x) = 14 x - 6

Find intervals:

Decreasing

: - \infty < x < \frac{3}{7},

Increasing

: \frac{3}{7} < x < \infty

Plug

x = \frac{3}{7}

into

4 x^{2} + 3 x^{2} - 6 x + 1 : - \frac{2}{7}

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