Bonjour,

1)

A(x) = 7 - x

A(10) = 7 - 10 = - 3

A(-3) = 7 - (-3) = 7 + 3 = 10

3)

C(a, b) = 7 - a + 5 + b

C(-2, -3) = 7 - (-2) + 5 + (-3) = 12 + 2 - 3 = 11

5)

E(a) = (a + 6) - (3 - a)

E(-5) = (-5 + 6) - (3 - (-5)) = 1 - (3 + 5) = 1 - 8 = -7

7)

G(x) = 2x² - 3x + 5

G(-5) = 2 * (-5)² - 3 * (-5) + 5 = 2 * 25 + 15 + 5 = 50 + 20 = 70
