bonjour
f (x) = 0.5 x - 2
f ( - 8) = - 8 * 0.5 - 2 = - 4 - 2 = - 6
f ( - 3) = - 3 * 0.5 - 2 = - 1.5 - 2 = - 3.5
f ( 2) = 2 * 0.5 - 2 = 1 - 2 = - 1
f ( 5) = 5 *0.5 - 2 = 2.5 - 2 = 0.5
5 ) f ( - 2) = 3
g ( 4) = - 5
( h 3) = - 5
f (0) = - 1
h ( - 3 ) = - 4 et h ( 4) = - 4
h ( 2 ) = 5 et h ( - 3) = 5
g ( - 1 ) = - 2
