Answer 1

-80

Penjelasan dengan langkah-langkah:

Diketahui:

• x = 2

Ditanya:

• f(x) = x³ + 4x - 3x⁵ = ...?

Jawab:

• f(x) = x³ + 4x - 3x⁵
• f(2) = 2³ + 4(2) - 3(2)⁵
• f(2) = 2³ + 4(2) - 3(2.2.2.2.2)
• f(2) = 2³ + 4(2) - 3(4.2.2.2)
• f(2) = 2³ + 4(2) - 3(8.2.2)
• f(2) = 2³ + 4(2) - 3(16.2)
• f(2) = 2³ + 4(2) - 3(32)
• f(2) = 2³ + 4(2) - (3.32)
• f(2) = 2³ + 4(2) - 96
• f(2) = 2³ + (4.2) - 96
• f(2) = 2³ + 8 - 96
• f(2) = (2.2.2) + 8 - 96
• f(2) = (4.2) + 8 - 96
• f(2) = 8 + (8 - 96)
• f(2) = 8 + -88
• f(2) = - (88 - 8)
• f(2) = -80

Kesimpulan:

Jadi, hasil dari f(x) = x³ + 4x - 3x⁵ adalah -80

Answer 2

f(x) = x³ + 4x - 3x⁵

f(2) = ?

• f(x) = x³ + 4x - 3x⁵
• f(2) = 2³ + 4(2) - 3(2)⁵
• f(2) = (2 × 2 × 2) + 4(2) - 3(2)⁵
• f(2) = (4 × 2) + 4(2) - 3(2)⁵
• f(2) = 8 + 4(2) - 3(2)⁵
• f(2) = 8 + (4 × 2) - 3(2)⁵
• f(2) = 8 + 8 - 3(2)⁵
• f(2) = 8 + 8 - 3(2 × 2 × 2 × 2 × 2)
• f(2) = 8 + 8 - 3(4 × 2 × 2 × 2)
• f(2) = 8 + 8 - 3(8 × 2 × 2)
• f(2) = 8 + 8 - 3(16 × 2)
• f(2) = 8 + 8 - 3(32)
• f(2) = 8 + 8 - (3 × 32)
• f(2) = 8 + 8 - 96
• f(2) = 16 - 96
• f(2) = -(96 - 16)
• f(2) = -80

koreksi
