Answer 1

Jawaban:

f(3) = 75

Penjelasan dengan langkah-langkah:

f(x) = x² + 3x³ - 5x

f(3) =

• f(3) = 3² + 3(3³) - 5(3)
• f(3) = (3×3) + 3(3×3×3) - 15
• f(3) = 9 + 3(27) - 15
• f(3) = 9 + 81 - 15
• f(3) = 90 - 15
• f(3) = 75

Answer 2

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

f(x) = x² + 3x³ - 5x

f(3) = 3² + 3(3)³ - 5(3)

f(3) = (3 × 3) + 3(3 × 3 × 3) - (5 × 3)

f(3) = 9 + 3(9 × 3) - 15

f(3) = 9 + 3(27) - 15

f(3) = 9 + 81 - 15

f(3) = 90 - 15

f(3) = 75
