extreme (x+4)/(x^2-5x-36)

解答

极值点

\frac{x + 4}{x ^{2} - 5 x - 36}

无

求解步骤

f^{'} (x) = - \frac{1}{( x - 9 ) ^{2}}

Find intervals:

无

无

e x t re m e f (x) = - \frac{5 x ^{3}}{3} + 10 x^{2} - 15 x, (- 2, 5)

e x t re m e f (x) = - 2 (- 3 x - 3) e^{- 2 x}

e x t re m e f (x, y) = x^{2} + y^{2} - x y - 2 x + y

e x t re m e f (x) = x^{3} - 2 x

e x t re m e f (x \cdot y) = 3 x^{2} - 4 x y + 3 y^{2} + 8 x - 17 y + 5
