f(x) = 3x + x!! - x × 4
f(4) = 3(4) + 4!! - 4 × 4
f(4) = (3 × 4) + (4 × 2) - (4 × 4)
f(4) = 12 + 8 - 16
f(4) = 12 - 8
f(4) = 4
f(4) = 12 + 4!! - 4 × 4
f(4) = 12 + (4 × 2) - 4 × 4
f(4) = 12 + 8 - 4 × 4
f(4) = 20 - 16

penyelesaian :
f(x) = 3x + x!! - x × 4
f(4) = 3(4) + 4!! - 4 × 4
f(4) = 12 + 4!! - 4 × 4
f(4) = 12 + (4 × 2) - 4 × 4
f(4) = 12 + 8 - 4 × 4
f(4) = 12 + 8 - 16
f(4) = 20 - 16
f(4) = 4
