Explications étape par étape
Bonjour
F(x) = 2x^2 + 3x - 3
F(0) = 2 * 0^2 + 3 * 0 - 3 = (-3)
F(1) = 2 * 1^2 + 3 * 1 - 3 = 2 + 3 - 3 = 2
F(-1) = 2 * (-1)^2 + 3 * (-1) - 3 = 2 - 3 - 3 = 2 - 6 = -4
F(-2) = 2 * (-2)^2 + 3 * (-2) - 3 = 8 - 6 - 3 = 8 - 9 = (-1)
F(3/5) = 2 * (3/5)^2 + 3 * (3/5) - 3 = 2 * 9/25 + 9/5 - 3 = 18/25 + 45/25 - 75/25 = 63/25 - 75/25 = 12/25
F(-1/4) = 2 * (-1/4)^2 + 3 * (-1/4) - 3 = 2 * 1/16 - 3/4 - 3 = 1/8 - 6/8 - 24/8 = 1/8 - 30/8 = -29/8
F(V3) = 2 * (V3)^2 + 3 * (V3) - 3 = 2 * 3 + 3V3 - 3 = 3 + 3V3
