untuk fungsi f(×)=-3×-5,dengan daerah asal A:{,-2,-1,0,1,2,3,4}.bayangan setiap anggota A adalah

f(x) = -3x -5.Domain A= {-2,-1,0,1,2,3,4}
f (-2) = -3.-2 -5 = 6 -5 = 1
f (-1) = -3.-1 -5 = 3 -5 = -2
f (0) = -3.0 -5 = 0 -5 = -5
f (1) = -3.1 -5 = -3 -5 = 8
f (2) = -3.2 -5 = -6 -5 = -11
f (3) = -3.3 -5 = -9 -5 = -14
f (4) = -3.4 -5 = -12 -5 = -17
Secara pasangan berurutan = { ( -2, 1 ), (-2, -2), (0, -5), (1, 8), (2, -11), (3, -14), (4, -17)}
