extreme y=-x^2-x-5

Solution

extreme

Solution

Maximum (- \frac{1}{2}, - \frac{19}{4})

Solution steps

f^{'} (x) = - 2 x - 1

Find intervals:

Increasing

: - \infty < x < - \frac{1}{2},

Decreasing

: - \frac{1}{2} < x < \infty

Plug

x = - \frac{1}{2}

into

- x^{2} - x - 5 : - \frac{19}{4}

Maximum (- \frac{1}{2}, - \frac{19}{4})
