Sagot :
bonjour
h (x) = 10 - 2 x
h (3) = 10 - 6 = 4
h ( 4) = 10 - 8 = 2
10 - 2 x = 0
- 2 x = - 10
x = 5
10 - 2 x = 4
- 2 x = 4 - 10
- 2 x = - 6
x = 3
10 - 2 x = - 5
- 2 x = - 5 - 10
- 2 x = - 15
x = 15/2
10 - 2 x = √2
- 2 x = √2 - 10
x = √2 : 2 + 5
Réponse:
1) h (3) = 10-2×3
h (3)= 4
h (4) = 10 -2×4
h (4)= 2
