Suatu fungsi f (x) =X2-9.tentukan rangenya jika dominannya {-2,-1,0,1,2,3}

1 Jawaban

  • domain = {-2,-1,0,1,2,3}
    f(x) = x² - 9
    range :
    f(-2) = (-2)²-9 = 4-9 = -5
    f(-1) = (-1)²-9 = 1-9 = -8
    f(0) = (0)²-9 = 0-9 = -9
    f(1) = (1)²-9 = 1 - 9 = -8
    f(2) = (2)²-9 = 4 -9 = -5
    f(3) = (3)²-9 = 9 -9 = 0

    daerah hasil = {0,-5,-8,-9}

    maaf kalo salah
