p(x) = - 7·x + 49
K(X)= x^3 - 6·x^2 + 15·x + 32
G(x) = x·p(x) - K(x) = x·(- 7·x + 49) - (x^3 - 6·x^2 + 15·x + 32) = - x^3 - x^2 + 34·x - 32
Gewinnschwelle/-grenze G(x) = 0
x = 1 oder x = 4.744562646 [oder x = -6.744562646]
Gewinnmaximum G'(x) = 0
x = 3.049630521 [oder x = -3.716297188]
G(3.049630521) = 34.02487638
