Q. ʕ•ﻌ•ʔf(x) = x² + x² – xf(2) = f(4) = ​

<< Penyelesaian >>

• f(x) = x² + x² – x

• f(2) = 2² + 2² – 2
• f(2) = 4 + 4 – 2
• f(2) = 6

• f(4) = 4² + 4² – 4
• f(4) = 16 + 16 – 4
• f(4) = 28

– Penyelesaian Soal –

• Diketahui

f(x) = x² + x² – x

• Ditanya

f(2) = ?

f(4) = ?

• Dijawab

• Hasil dari f(2)

• f(2) = 2² + 2² – 2
• f(2) = ( 2 × 2 ) + ( 2 × 2 ) – 2
• f(2) = 4 + 4 – 2
• f(2) = 8 – 2
• f(2) = 6

• Hasil dari f(4)

• f(4) = 4² + 4² – 4
• f(4) = ( 4 × 4 ) + ( 4 × 4 ) – 4
• f(4) = 16 + 16 – 4
• f(4) = 32 – 4
• f(4) = 28

Kesimpulan

• Hasil dari f(2) = 6
• Hasil dari f(4) = 28
