- f(x) = 90x × x!! + x³
- f(7) = ...
___________________________
f(7) = 90(7) × 7!! + 7³
f(7) = ( 90 × 7 ) × ( 7 × 5 × 3 × 1 ) + ( 7 × 7 × 7 )
f(7) = 630 × 105 + 343
f(7) = 66.150 + 343
f(7) = 66.493 ☑
Papay-!

penyelesaian :
f(x) = 90x × x!! + x^3
f(7) = 90(7) × 7!! + 7^3
f(7) = 630 × (7 × 5 × 3 × 1) + 7^3
f(7) = 630 × (35 × 3 × 1) + 7^3
f(7) = 630 × (105 × 1) + 7^3
f(7) = 630 × 105 + 7^3
f(7) = 630 × 105 + (7 × 7 × 7)
f(7) = 630 × 105 + (49 × 7)
f(7) = 630 × 105 + 343
f(7) = 66.150 + 343
f(7) = 66.493
