Soal
f(x) = 78x + 2x²
f(3!! ) =
Hasil
252
Penyelesaian
f(x) = 78x + 2x²
f(3!! ) = 78x + 2x²
f( 3 × 1 ) = 78x + 2x²
f(3) = 78x + 2x²
f(3) = 78(3) + 2x²
f(3) = ( 78 × 3 ) + 2x²
f(3) = 234 + 2x²
f(3) = 234 + 2(3)²
f(3) = 234 + 2( 3 × 3 )
f(3) = 234 + 2(9)
f(3) = 234 + ( 2 × 9 )
f(3) = 234 + 18
f(3) = 252

Jawaban:
f(3!!) = 78(3) + 2(3)²
= 234 + 2(9)
= 234 + 18
= 252
