f(x) = (x+5)^3 * e^(x/2)^3

чему равно d(f(x))/dx ?

d(f(x))/dx=f'(x)=lim(deltaX->0)[(f(x+deltaX)-f(x))/deltaX].

Замечательная весч Вольфрам Математика.

d(f(x))/dx=3 у^(3 x/2) (5 + x)^2 + 3/2 у^(3 x/2) (5 + x)^3

А вот график:


d(f(x))/dx=3 e^(3 x/2) (5 + x)^2 + 3/2 e^(3 x/2) (5 + x)^3
гы, лол.
вместо у экспонента.

На самом деле легко выводится если применить правило вычисления производных двух функций.
(U*V)' = U'V + V'U
