Sagot :

Bonjour,

1) f(x) = -x²+3

  donc :

  • f(-4) = -(-4)²+3 = -13
  • f(-3) = -(-3)²+3 = -6
  • f(-2) = -(-2)²+3 = -1
  • f(-1) = -(-1)²+3 = 2
  • f(0) = -(0)²+3 = 3
  • f(1) = -(1)²+3 = 2
  • f(2) = -(2)²+3 = -1
  • f(3) = -(3)²+3 = -6
  • f(4) = -(4)²+3 = -13
  • f(5) = -(5)²+3 = -22

2) et 3) voir pièces jointes
