Answer 1

Jawaban:

f'(2) = 172

Penjelasan dengan langkah-langkah:

f(x) = 5x³ + 4x² + 3x⁶ ÷ 2 + 2x⁴ - 5

f'(2) = 5(2)³ + 4(2)² + 3(2)⁶ ÷ 2 + 2(2)⁴ - 5 masukan / ganti x dengan angka 2

f'(2) = (5×8) + (4×4) + (3×64) ÷ 2 + (2×16) -5

f'(2) = 40 + 16 + 192 ÷ 2 + 32 -5 kerjakan pembagian terlebih dahulu

f'(2) = 40 + 16 + 96 +32 - 5

f'(2) = 184-5

f'(2) = 179

Answer 2

Diketahui:

→ f(x) = 5x³ + 4x² + 3x⁶ ÷ 2 + 2x⁴ - 5

Ditanya:

→ f(2) = ?

===========================================

PENYELESAIAN :

• f(x) = 5x³ + 4x² + 3x⁶ ÷ 2 + 2x⁴ - 5

• f(2) = 5(2)³ + 4(2)² + 3(2)⁶ ÷ 2 + 2(2)⁴ - 5

• f(2) = 5(8) + 4(4) + 3(64) ÷ 2 + 2(16) - 5

• f(2) = (5 × 8) + (4 × 4) + (3 × 64) ÷ 2 + (2 × 16) - 5

• f(2) = 40 + 16 + 192 ÷ 2 + 32 - 5

• f(2) = 40 + 16 + 96 + 32 - 5

• f(2) = 56 + 128 - 5

• f(2) = 184 - 5

• f(2) = 179

Kesimpulan:

• f(2) = 179
