extreme f(x)=5-6x-4x^2

Solution

extreme

Solution

Maximum (- \frac{3}{4}, \frac{29}{4})

Solution steps

f^{'} (x) = - 8 x - 6

Find intervals:

Increasing

: - \infty < x < - \frac{3}{4},

Decreasing

: - \frac{3}{4} < x < \infty

Plug

x = - \frac{3}{4}

into

5 - 6 x - 4 x^{2} : \frac{29}{4}

Maximum (- \frac{3}{4}, \frac{29}{4})
