Bonsoir,
f(0) = 2 x 0^2
f(0) = 2 x 0
f(0) = 0
f(-1) = 2 x -1^2
f(-1) = 2 x -1
f(-1) = -2
f(2) = 2 x 2^2
f(2) = 2 x 4
f(2) = 8
f(-2) = 2 x -2 ^2
f(-2) = 2 x -4
f(-2) = -8

F(x) = 2x*
F(0) = 2(0)* = [0]
F(-1) = 2(-1)* = [2]
F(2) = 2(2)* = (2)*=4 Donc ; 2(4) = [8]
F(-2)= 2(-2)* = (-2)*=4 Donc ; 2(4) = [8]
