f(x)=4x-7 dengan daerah asal={-2,-1,0,1,2,3},tentukan range fungsi tersebut

2 Jawaban

  • f (x) = 4x - 7
    f (-2) = 4.-2 - 7 = -8-7 = -15
    f (-1) = 4.-1 - 7 = -4 - 7 = -11
    f (0) = 4.0 - 7 = 0 - 7 = -7
    f (1) = 4.1 - 7 = 4 - 7 = -3
    f (2) = 4.2 - 7 = 8 - 7 = 1
    f (3) = 4.3 - 7 = 12 - 7 = 5
