Answer 1

» penyelesaian

• f(x) = x² + 20 + 4x²
• f(3) = 3² + 20 + 4(3)²
• f(3) = (3 x 3) + 20 + 12²
• f(3) = 9 + 20 + (12 x 12)
• f(3) = 29 + 144
• f(3) = 173

-------------------------------------------

kesimpulan :

hasil

f(3) = 173

Answer 2

Penyelesaian

• f(x) = x² + 20 + 4x²
• f(3) = 3² + 20 + 4(3)²
• f(3) = ( 3×3 ) + 20 + ( 4×3x )²
• f(3) = 9 + 20 + 12²
• f(3) = 9 + 20 + ( 12×12 )
• f(3) = 9 + 20 + 144
• f(3) = 29 + 144
• f(3) = 173 ✅
