Bonjour,
1)
B(x) = R(x) - C(x)
B(x) = 7,9x - (5x² - 0,1x + 1)
B(x) = -5x² + 8x - 1
2)
α = -b/2a = -8/(-5 * 2) = -8/-10 = 0,8
β = f(α) = -5 * 0,8² + 8 * 0,8 - 1 = 2,2
B(x) = -5 (x - 0,8)² + 2,2
3) Le benefice journalier maximum que l'entreprise peut realiser est de 220 euros pour 80 etuis fabriques et vendus par jour
