Answer 1

2.060

Penjelasan dengan langkah-langkah:

Diketahui:

• x = 4

Ditanya:

• f(x) = 3x + 8(x) × x³ = ... ?

Jawab:

• f(x) = 3x + 8(x) × x³
• f(4) = 3(4) + 8(4) × 4³
• f(4) = 3(4) + 8(4) × (4.4.4)
• f(4) = 3(4) + 8(4) × (16.4)
• f(4) = 3(4) + 8(4) × 64
• f(4) = 3(4) + (8.4) × 64
• f(4) = 3(4) + 32 × 64
• f(4) = (3.4) + 32 × 64
• f(4) = 12 + (32 × 64)
• f(4) = 12 + 2.048
• f(4) = 2.060

Kesimpulan:

Jadi, hasil dari f(x) = 3x + 8(x) × x³ adalah 2.060

Answer 2

Jawaban:

Diketahui:

• f(x) = 3x + 8(x) × x³

Ditanya:

• Jika f(4) maka …

Jawab:

f(x) = 3x + 8(x) × x³

f(4) = 3.4 + 8(4) × 4³

= 12 + 32 × (4×4×4)

= 12 + 32 × (16×4)

= 12 + 32 × 64

= 12 + 2.048

= 2.060

Jadi, nilai dari f(4) adalah 2.060
