Answer 1

Penyelesaian :

• f(x) = 5x + x!! - x

• f(10) = 5(10) + 10!! - 10

• f(10) = ( 5 × 10 ) + 10!! - 10

• f(10) = 50 + ( 10 × 8 × 6 × 4 × 2 ) - 10

• f(10) = 50 + ( 80 × 6 × 4 × 2 ) - 10

• f(10) = 50 + ( 80 × 24 × 2 ) - 10

• f(10) = 50 + ( 1.920 × 2 ) - 10

• f(10) = ( 50 + 3.840 ) - 10

• f(10) = 3.890 - 10

• f(10) = 3.880

Answer 2

Penyelesaian

f(x) = 5x + x!! - x

f(10) = 5(10) + 10.8.6.4.2 - (10)

f(10) = 5(10) + 80.24.2 - (10)

f(10) = 5(10) + ( 1.920 x 2 ) - 10

f(10) = ( 5 x 10 ) + ( 1.920 x 2 ) - 10

f(10) = 50 + 3.840 - 10

f(10) = 3.890 - 10

f(10) = 3.880
