extreme Y(s)=(α^1)/s+(α^2)/(2s+6)

extreme

Maximum (- 6, - \frac{1}{2})

Solution steps

Find the critical points:

(- 6, - \frac{1}{2})

\frac{\partial ^{2} f}{\partial s ^{2}} = \frac{1}{s + 3}

D (s, α) = \frac{- s ^{6} + 6 s ^{5} α - 18 s ^{5} + 72 s ^{4} α - 135 s ^{4} + 324 s ^{3} α - 540 s ^{3} + 648 s ^{2} α - 1215 s ^{2} + 486 s α - 1458 s - 729}{s ^{4} ( s + 3 ) ^{6}}
