bonjour
f (x) = - 6 x + 3
f ( 1) = - 6 + 3 = - 3
f ( - 3 ) = 18 + 3 = 21
f ( 0 ) = 3
f ( 1.5 ) = - 9 + 3 = - 6
- 6 x + 3 = 3
- 6 x = 3 - 3
- 6 x = 0
0
g (x ) = 2 x² - 3 x
g ( 3 ) = 2 * 9 - 9 = 18 - 9 = 9
g ( - 2 ) = 4 + 6 = 10
g ( - 3 ) = 18 + 9 = 27
h (x) = 3 x²
h ( 5 ) = 3 *25 = 75
h ( - 4 ) = 3 * 16 = 48
h ( 0 ) = 0
