  • F : x -> 9x + 2 
    domain= { x| -2<x≤ 4 xB } 
    domain = { -1,0,1,2,3,4}

    gunakan f(x) = 9x + 2
    f(-1) = 9x + 2
            = 9(-1) + 2
            = -9 + 2
            = -7
    f(0) = 9(0) + 2
         = 0 + 2
          = 2
    f(1) = 9 + 2
          = 11
    f(2) = 18 + 2
          = 20
    f(3) = 27 + 2
          = 29
    f(4) = 36 + 2
          = 38

    Jadi, rangenya = {-7, 2, 11, 20, 29, 38}
