bonjour
tu calcules 2 images de chaque
f (x) = 4 x /3 - 2
f ( 0) = - 2
f ( 3 ) = 12/3 - 2 = 4 - 2 = 2
g (x) = - 5 x / 7
g ( 0) = 0
g ( 2 ) = - 10 /7
h (x) = ( - x + 11 ) / 6
h ( 1 ) = ( - 1 + 11 ) / 6 = 10/6 = 5 /3
h ( - 1 ) = 12 /6 = 2
k (x) = 7 x /5 - 1 /5
k (0) = - 1 /5
k ( 1 ) = 7/5 - 1/5 = 6 /5
