Diketahui:

f(x)=x³ + x! + x² × ⅜

Ditanya:

f'(5)=….?

Dijawab:

f(x)=x³ + x! + x² × ⅜

f(x)=x³ + x! + x² × ⅜f'(5)=….?

• f(5) = x³ + x! + x² × ⅜
• f(5) = 5³ + 5! + 5² × ⅜
• f(5)= ( 5 × 5 × 5 ) + ( 5 × 4 × 3 × 2¹ ) + ( 5 × 5 ) × ⅜
• f(5) = ( 25 × 5 ) + ( 20 × 6¹) + ( 25 ) × ⅜
• f(5) = ( 125 + 120 + ) ( 25 × ⅜ )
• f(5) = ( 245 + ( 25 × ⅜ )
• f(5) = ( 245 +( 25 × ⅜)
• f(5) = ( 245 ( 25 × ⅜ )
• 
• 
• 
• 
• f(5) = 245 + 9.375
• f(5) = 254.375

[ Kesimpulan ]

• Hasil dari f(5) = 254.375
