Pouvez vous m’aider pour cet exercice

Bonsoir

f (x) = 7 x + 6

f ( 6) = 42 + 6 = 48

f (2) = 14 + 6 = 20

g (x) = 4 x² + 9 x - 4

g ( 5) = 4 *25 + 9*5 - 4 = 100 + 45 - 4 = 141

g ( - 4 ) = 4 ( - 4 ) ² + 9 *-4 - 4 = 64 - 36 - 4 = 24

h ( 1) = - 1

h ( 3 ) = - 4

h 0) = 3

h ( 2 ) = 0

k ( - 3 ) = 3

k ( 3) = 0

k ( 1) = - 2

k ( - 2 ) = - 3
