◇ DIKETAHUI

• f(3)

◇ DITANYA

• f(x) = 4x - 7x × 2x - 10

◇ JAWAB

• f(x) = 4x - 7x × 2x - 10
• f(3) = 4(3) - 7(3) × 2(3) - 10
• f(3) = ( 4 × 3 ) - 7(3) × 2(3) - 10
• f(3) = ( 12 ) - ( 7 × 3 ) × 2(3) - 10
• f(3) = 12 - ( 21 ) × ( 2 × 3 ) - 10
• f(3) = 12 - 21 × ( 6 ) - 10
• f(3) = 12 - ( 21 × 6 ) - 10
• f(3) = 12 - ( 126 ) - 10
• f(3) = 12 - 126 - 10
• f(3) = -114 - 10
• f(3) = -124

◇ KESIMPULAN

• Maka bisa di bilang hasil dari f(3) adalah -124

Answer 2

f(x) = 4x - 7x × 2x - 10

f(3) = 4(3) - 7(3) × 2(3) - 10

f(3) = ( 4 × 3 ) - ( 7 × 3 ) × ( 2 × 3 ) - 10

f(3) = 12 - ( 21 × 6 ) - 10

f(3) = 12 - 126 - 10

f(3) = -114 - 10

f(3) = -124
