Q.

f(x) = 3x + 7x × x!!
f(3) =

pakai cara ​

Answer 1

f(3) = 72

Penjelasan dengan langkah-langkah:

x = 3

f(x) = 3x + 7x × x!!

• f(3) = 3(3) + 7(3) × 3!!
• f(3) = 3(3) + 7(3) × (3.1)
• f(3) = 3(3) + 7(3) × 3
• f(3) = 3(3) + (7.3) × 3
• f(3) = 3(3) + 21 × 3
• f(3) = (3.3) + 21 × 3
• f(3) = 9 + (21 × 3)
• f(3) = 9 + 63
• f(3) = 72

Answer 2

f(x) = 3x + 7x × x!!

f(3) = 3(3) + 7(4) × 3!!

f(3) = ( 3 × 3 ) + ( 7 × 3 ) × ( 3 × 1 )

f(3) = 9 + 21 × 3

f(3) = 9 + ( 21 × 3 )

f(3) = 9 + 63

f(3) = 72
