Sagot :
bonjour
h (x) = 3 x + 2
3 x + 2 = 1
3 x = 1 - 2
3 x = - 1
x = - 1/3
f ( 12 ) = 36 + 2 = 38 donc faux
h ( 10) = 30 + 2 = 32
h ( - 10 ) = - 30 + 2 = - 28
Bonjour,
h(x)= 3x+2
1) résoudre:
3x+2= 1
x=(1-2)/3
x= -1/3
2) f(12) =3(12)+2 = 38 faux
3) Calcul de :
h(10)= 3(10)+2= 32
h(-10)= 3(-10=+2= -30+2= -28
