y.
f(x) = 12x × x!! + x³
f(9) = 12(9) × 9!! + 9³
f(9) = 108 × ( 9 × 7 × 5 × 3 × 1 ) + (( 9 × 9 ) × 9 ))
f(9) = 108 × ( 63 × 15 ) + ( 81 × 9 )
f(9) = 108 × 945 + 729
f(9) = 102060 + 729
f(9) = 102.789

f(x) = 12x × x!! + x³
f(9) = 12.9 × 9!! + 9³
= 108 × (9.7.5.3.1) + (9.9.9)
= 108 × 945 + 729
= 102.060 + 729
= 102.789
