a.buatlah daftar fungsi tersebut dari {-3,-2,-1,0,1,2,3,4}

2 Jawaban

  • F(-3) = 2(-3) + 1 = -6 + 1 = -5
    F(-2) = 2(-2) + 1 = -4 + 1 = -3
    F(-1) = 2(-1) + 1 = -2 + 1 = -1
    F(0) = 2(0) + 1 = 0 + 1 = 1
    F(1) = 2(1) + 1 = 2 + 1 = 3
    F(2) = 2(2) + 1 = 4 + 1 = 5
    F(3) = 2(3) + 1 = 6 + 1 = 7
    F(4) = 2(4) + 1 = 8 + 1 = 9
  • {-5,-3,-1,1,3,5,7,9} kalau tidak salah
