f(x) = 5 - 3x
f(-2) = 5 - 3(-2) = 5 - (-6) = 5 + 6 = 11
f(-1) = 5 - 3(-1) = 5 - (-3) = 5 + 3 = 8
f(0) = 5 - 3(0) = 5 - 0 = 5
f(1) = 5 - 3(1) = 5 - 3 = 2
f(2) = 5 - 3(2) = 5 - 6 = -1
f(3) = 5 - 3(3) = 5 - 9 = -4
himpunan pasangan berurutan dari fungsi tersebut adalah {(-2, 11), (-1, 8), (0, 5), (1, 2), (2, -1), (3, -4)}
