bonjour
prendre 2 images de chaque fonction
f (x) = 4 x /3 - 2
f ( 0) = - 2
f ( 3 ) = 12/3 - 2 = 4 - 2 = 2
tu as 2 points ( 0 : - 2 ) et ( 3 ; 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
k (x) = 7 x /5 - 1 /5
k ( 0 ) = - 1 /5
k ( 3)= 21/5 - 1/5 = 20/5 = 4
