Bonsoir,

f (x) = - 3x + 2

a. 1

f (x) = - 3x + 2

f (1) = - 3 * 1 + 2

f (1) = - 3 + 2

f (1) = - 1

b. 0

f (x) = - 3x + 2

f (0) = - 3 * 0 + 2

f (0) = 0 + 2

f (0) = 2

c. - 2

f (x) = - 3x + 2

f (- 2) = - 3 * (- 2) + 2

f (- 2) = 6 + 2

f (- 2) = 8

d. 2/3

f (x) = - 3x + 2

f(2/3) = - 3 * 2/3 + 2

f (2/3) = - 6/3 + 2

f (2/3) = - 2 + 2

f (2/3) = 0.

Bonjour

Explications étape par étape

f(x) = -3x + 2

Calculer l’image :

f(1) = -3 * 1 + 2 = -3 + 2 = -1

f(0) = -3 * 0 + 2 = 0 + 2 = 2

f(-2) = -3 * -2 + 2 = 6 + 2 = 8

f(2/3) = -3 * 2/3 + 2 = -2 + 2 = 0
