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
Bonsoir
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]
