Réponse :
bonsoir
il faut calculer des images
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 ( 7 ) = - 35/7 = - 5
h ( x )= (- x + 11 ) /6
h (- 1 ) = 12/6 = 2
h ( 2) = 9/6 = 3 /2 = 1.5
k (x) = 7 x /5 - 1 /5
k ( 3 ) = 21/5 - 1/5 = 20/5 = 4
k ( 2 ) = 14/5 - 1/5 = 13/5
