Answer 1

f(x) = x² + 5x + x!

f(5) = 5² + 5.5 + 5!

= (5 × 5) + (5 × 5) + (5 × 4 × 3 × 1)

= 25 + 25 + 120

= 50 + 120

= 170

Answer 2

170

Penjelasan dengan langkah-langkah:

Diketahui:

• x = 5

Ditanya:

• f(x) = x² + 5x + x! = ... ?

Jawab:

• f(x) = x² + 5x + x!
• f(5) = 5² + 5(5) + 5!
• f(5) = 5² + 5(5) + (5.4.3.2.1)
• f(5) = 5² + 5(5) + (20.3.2.1)
• f(5) = 5² + 5(5) + (60.2.1)
• f(5) = 5² + 5(5) + (120.1)
• f(5) = 5² + 5(5) + 120
• f(5) = 5² + (5.5) + 120
• f(5) = 5² + 25 + 120
• f(5) = (5.5) + 25 + 120
• f(5) = 25 + 25 + 120
• f(5) = 25 + 145
• f(5) = 170

Kesimpulan:

Jadi, hasil dari f(x) = x² + 5x + x! adalah 170
