Q.
f(x) = x² + x!! - 5
f(5) = ...
![]()
f(x) = x² + x!! - 5
f(5) = ...
Penjelasan dengan langkah-langkah:
f(x) = x² + x!! - 5
f(5) = 5² + 5!! - 5
f(5) = ( 5 × 5 ) + 5!! - 5
f(5) = 25 + ( 5 × 3 × 1 ) - 5
f(5) = 25 + ( 15 × 1 ) - 5
f(5) = 25 + 15 - 5
f(5) = 25 + 10
f(5) = 35
f(x) = x² + x!! - 5
f(5) = 5² + 5!! - 5
f(5) = ( 5 × 5 ) + ( 5 × 3 × 1 ) - 5
f(5) = 25 + 15 - 5
f(5) = 40 - 5
f(5) = 35
