f(x) = x + 2x + 3x + 4x - x!
f(6) = 6 + 2(6) + 3(6) + 4(6) - 6!
f(6) = 6 + (2.6) + (3.6) + (4.6) - (6.5.4.3.2.1)
f(6) = 6 + 12 + 18 + 24 - 720
f(6) = 60 - 720
f(6) = -660
Penyelesaian :
f(x) = x + 2x + 3x + 4x - x!
f(6) = 6 + 2(6) + 3(6) + 4(6) - (6 × 5 × 4 × 3 × 2 × 1)
f(6) = 6 + 12 + 18 + 24 - (30 × 4 × 3 × 2 × 1)
f(6) = 18 + 18 + 24 - (120 × 3 × 2 × 1)
f(6) = 36 + 24 - (360 × 2 × 1)
f(6) = 60 - (720 × 1)
f(6) = 60 - 720
f(6) = -660
