Bonjour !

1)

$f(2) = - 2 \times 2 = - 4$

$f( - 5) = - 2 \times - 5 = 10$

$f(0) = - 2 \times 0 = 0$

$f( \frac{3}{2} ) = - 2 \times \frac{3}{2} = - 3$

$f( \frac{ - 7}{4} ) = - 2 \times \frac{ - 7}{4} = \frac{7}{2}$

2) Voir image, c'est une droite donc tu peux la retracer en prenant deux points.

3)

$f(a) = 12 \\ - 2a = 12 \\ a = \frac{12}{ - 2} = - 6$

Donc a = -6.

4)

$f(x) = x + 12 \\ - 2x = x + 12 \\ - 3x = 12 \\ x = \frac{12}{ - 3} = - 4$

Donc x = -4

Bonne journée
