coût fixes = C(0)]]> 2018-02-22 13:55:39 UTC https://padlet.com/magali_renou1/4fr2w1id90f0/wish/234209480 Dérivée https://padlet.com/magali_renou1/4fr2w1id90f0/wish/235274816 Si B(x) = -15x^3 +120^2+180x-1000
 Alors B'(x) = -15*3x^2+120*2x+180-0
Donc B'(x)= -45x^2+240x+180]]> 2018-02-26 10:18:22 UTC https://padlet.com/magali_renou1/4fr2w1id90f0/wish/235274816 Exemple tableau de variations magali_renou1 https://padlet.com/magali_renou1/4fr2w1id90f0/wish/235276735 B'(x)=0 <=> -45x²+240x+180=0
