f(x) = x² + x! - 4(x) + 2¹
f(5) = 5² + 5! - 4(5) + 2 × 1
f(5) = ( 5 × 5 ) + ( 5 × 4 × 3 × 2 × 1 ) - ( 4 × 5 ) + 2
f(5) = 25 + ( 20 × 3 × 2 × 1 ) - 20 + 2
f(5) = 25 + ( 60 × 2 × 1 ) - 20 + 2
f(5) = 25 + 120 - 20 + 2
f(5) = 145 - 20 + 2
f(5) = 125 + 2
f(5) = 127
f(x) = 6x + x!! × x²
f(6) = 6(6) + 6!! × 6²
f(6) = ( 6 × 6 ) + ( 6 × 4 × 2 ) × ( 6 × 6 )
f(6) = 36 + ( 24 × 2 ) × 36
f(6) = 36 + 48 × 36
f(6) = 36 + 1728
f(6) = 1.764
~Koreksi~
Jawaban:
1. f(5) = 127
2. f(6) = 1.764
Penjelasan dengan langkah-langkah:
Nomor 1
f(5) = 5² + 5! - 4(5) + 2¹
f(5) = (5 × 5) + (5 × 4 × 3 × 2 × 1) - (4 × 5) + 2
f(5) = 25 + (20 × 3 × 2 × 1) - 20 + 2
f(5) = 25 + (60 × 2 × 1) - 20 + 2
f(5) = 25 + (120 × 1) - 20 + 2
Nomor 2
f(6) = (6 × 6) + (6 × 4 × 2) × (6 × 6)
f(6) = 36 + (24 × 2) × 36
f(6) = 36 + 1.728
