extreme f(x)=-3x^2+5x-4

Solution

extreme points

f (x) = - 3 x^{2} + 5 x - 4

Solution

Maximum (\frac{5}{6}, - \frac{23}{12})

Solution steps

f^{'} (x) = - 6 x + 5

Find intervals:

Increasing

: - \infty < x < \frac{5}{6},

Decreasing

: \frac{5}{6} < x < \infty

Plug

x = \frac{5}{6}

into

- 3 x^{2} + 5 x - 4 : - \frac{23}{12}

Maximum (\frac{5}{6}, - \frac{23}{12})
