f(x) = 3x + 8

si x = -3 → f(-3) 3 x -3 + 8 = -1

si x = -2 → f(-2) = 3 x - 2 + 8 = 2

f(x) = 2 → quelque soit x sur l'intervalle  -2 ≤ x ≤-1 → f(x) = 2

f(x) = -x + 1

si x = -1 → f(-1) = +1 + 1 = 2

si x = 0 → f(0) = 0 + 1 = 1

si x = 1 → f(1) = -1 + 1 = 0

si x = 2 → f(2) = -2 + 1 = -1

f(x) = 2x - 5

si x = 2 → f(2) = 2 x 2 - 5 = -1

si x = 4 → f(4) = 2 x 4 - 5 = -3

bonne aprèm
