Salut!

Soit f ( x ) = - x - 2

Calcul de :

=> f ( -5)

f ( -5) = - (-5) - 2

f ( -5 ) = 5 - 2

f ( -5 ) = 3

=> f ( -3)

f ( -3 ) = - ( -3 ) - 2

f ( -3 ) = 3 - 2

f ( -3 ) = 1

=> f ( 0 )

f (0) = -(0) - 2

f ( 0 ) = -2

=> f ( 1 )

f ( 1 ) = -( 1 ) - 2

f ( 1 ) = -1 - 2

f ( 1 ) = -3

=> f ( 2 )

f ( 2 ) = - (2) - 2

f ( 2) = -2 - 2

f( 2 ) = -4

J'espère que cela vous aidera !

Bonne journée :)))
