Jawab:
f(x) = x! + x² - x
f(5) = 140
Penjelasan dengan langkah-langkah:
f(5) = 5! + 5² - 5
f(5) = (5 × 4 × 3 × 2 × 1) + (5 × 5) - 5
f(5) = 120 + 25 - 5
f(5) = 145 - 5
x! + x² - x
f(5) = ...
f(5) = ( 5 × 4 × 3 × 2 × 1 ) + 5² - 5
f(5) = ( 20 × 3 × 2 × 1 ) + 5² - 5
f(5) = ( 60 × 2 × 1 ) + 5² - 5
f(5) = ( 120 × 1 ) + 5² - 5
f(5) = 120 + 5² - 5
f(5) = 120 + ( 5 × 5 ) - 5
f(5) = 120 + 20
jadi hasil sari f(5) adalah 140.

Diketahui :
x! + x² - x
Ditanya :
f(5) = ...
Jawab :
f(5) = 5! + 5² - 5
f(5) = ( 5 × 4 × 3 × 2 × 1 ) + 5² - 5
f(5) = ( 20 × 3 × 2 × 1 ) + 5² - 5
f(5) = ( 60 × 2 × 1 ) + 5² - 5
f(5) = ( 120 × 1 ) + 5² - 5
f(5) = 120 + 5² - 5
f(5) = 120 + ( 5 × 5 ) - 5
f(5) = 120 + 25 - 5
f(5) = 120 + 20
f(5) = 140
Kesimpulan :
jadi hasil sari f(5) adalah 140.
