Diketahui F:x-73x+2 dengan daerah domain {-3,-2,-1,0,1,2,3} tentukan daerah Hasil Range

Bab Fungsi
Matematika SMP Kelas VIII

f(x) = -73x + 2

f(-3) = -73 . (-3) + 2
       = 219 + 2
       = 221

f(-2) = -73 . (-2) + 2
        = 146 + 2
        = 148

f(-1) = -73 . (-1) + 2
        = 73 + 2
        = 75

f(0) = -73 . 0 + 2
      = 0 + 2
      = 2

f(1) = -73 . 1 + 2
      = -73 + 2
      = -71

f(2) = -73 . 2 + 2
       = -146 + 2
      = -144

f(3) = -73 . 3 + 2
      = -219 + 2
      = -217

Range = { -219, -144, -71, 2, 73, 146, 221 }
