bonjour
f (x) = - 5 x - 4
f ( - 5 ) = - 5 * - 5 - 4 = 25 - 4 = 21
g (x) = 2 x² - 4 x + 4
g ( - 2) = 2 ( - 2 )² - 4 * - 2 + 4 = 8 + 8 + 4 = 20
h (x) = ( 3 x + 2 )²
h ( - 2 ) = ( - 6 + 2 )² = ( - 4 )² = 16
i (x) = ( - 3 x + 3 ) ( - 2 x + 4 )
i ( - 1 ) = ( 3 + 3 ) ( - 2 + 4 ) = 6 * 2 = 12
j (x) = 6 x + 6 / - 3 x + 12
j ( 2 ) = ( 12 + 6 ) / ( - 6 + 24 ) = 18/ 18 = 1
k (x) = 12 x - 3
k ( 7/3 ) = 84/3 - 3 = 28 - 3 = 25
l ( x) = 2 x² + 7 x + 2
l ( 1) = 2 + 7 + 2 = 11
m (x) = - 6 x + 6
m ( 1/6 ) = - 6/6 + 6 = - 1 + 6 = 5
