1) Soit P le prix initial, P₁ = le prix après la baisse de 10% et P₂ = valeur finale:
P₁ = P-10%.P →→ P₁ = P(1-0.1) →→P₁ = 0.9.P
P₂ = P₁ + 10%P₁ →→P₂ = P₁(1+0.1) →→P₂ = 1.1P₁
Mais P₁ = 0.9.P→→P₂ = (1.1)(0.9)P
Donc P₂ = (0.99).P [99% of the original price)
2) P = prix initial et P₁ = prix après hausse de 25% .Donc:
P₁ = P(1+.25) →→P₁ = 1.25P.Pour retrouver le prix initial P, on divise le prix P₁ (après la hausse) par 1.25. Dou P = P₁/1.25
3) f(x) = (2x-3)(1-4x) g(x) =-2(x-3)² - 9
f(x) = 2x-8x²-3+12x →→f(x) = -8x² + 14x -3
g(x) = 2(x² - 6x + 9) + 9 →→ g(x) = 2x² - 12x +18 + 9
g(x) = 2x² - 12x +27
