Q
Jwb :
f(x) = x² × 2x + x!!
f(7) = 7² × 2(7) + 7!!
f(7) = (7 × 7) × 2(7) + 7!!
f(7) = 49 × 2(7) + 7!!
f(7) = 49 × (2 × 7) + 7!!
f(7) = 49 × 14 + 7!!
f(7) = 49 × 14 + 7 × 5 × 3 × 1
f(7) = 49 × 14 + 35 × 3 × 1
f(7) = 49 × 14 + 105 × 1
f(7) = 49 × 14 + 105
f(7) = 686 + 105
f(7) = 791
Jawaban:
f(x) = x² × 2x + x!!
f(7) = 7² × 2(7) + 7!!
f(7) = (7 × 7) × (2 × 7) + (7 × 5 × 3 × 1)
f(7) = 49 × 14 + 105
f(7) = 686 + 105
f(7) = 791
