Réponse:
[tex]f( - 2) = \frac{ - 2}{3} - 3 = - 2.33 \\ h( - 2) = - 6 \times- 2- (3 \times - 2) =12+6 = 18 \\ j( - 2) =5 \times 4 - 2 = 20 - 2 = 18[/tex]
g( 2/5)= -4/ 5
k(-8/3)=( - 12 / 8 )+2 = -1.5+2 = 0.5
exercice 2:
[tex]g(x) = - 2x = 6 \\ x = - 3 \\ h(x) = - 6 - 3x = 12 \\ - 3x = 18 \\ x = - 6 \\ \\ k(x) = \frac{4}{x} + 2 = - 8 \\ \frac{4}{x} = 10 \\ x = \frac{4}{10} = 0.4[/tex]
