Sagot :
bonjour
f (x) = 3 x - 20
f ( - 10) = - 10 *3 - 20 = - 30 - 20 = - 50
f ( - 5 ) = - 5 * 3 - 20 = - 15 - 20 = - 35
f ( 0) = - 20
f ( 5) = 15 - 20 = - 5
f ( 10) = 30 - 20 = 10
bjr
f ( x ) = 3x - 20
f (-10) = -30 - 20 = -50
f (-5) = -15 - 20 = -35
f(0) = -20
f(5) = 15-20 = -5
f ( 10) = 10
bonne journée
