Em....Apa Yang Mau Di Koreksi Kak Melvin TvT .​ f(x) = x!! × 7(x) + 8² – 2(x)
f(4) = 4!! × 7(4) + 8² – 2(4)
f(4) = (4 × 2) × 7(4) + 8² – 2(4)
f(4) = 8 × 28 + (8 × 8) – 8
f(4) = 8 × 28 + 64 – 8
f(4) = 224 + 64 – 8
f(4) = 288 – 8
f(4) = 280 ✓

f(6) = x!! × 7(x) + 8² – 2(x)
f(6) = 6!! × 7(6) + 8² – 2(6)
f(6) = (6 × 4 × 2) × 7(6) + 8² – 2(6)
f(6) = (24 × 2) × 7(6) + 8² – 2(6)
f(6) = 48 × 42 + (8 × 8) – 12
f(6) = 48 × 42 + 64 – 12
f(6) = 2.016 + 64 – 12
f(6) = 2.080 – 12
f(6) = 2.068 ✓

⟩ f(4) + f(6)
= 280 + 2.068
= 2.348 ✓

๑ Kesimpulan

⟩ f(4) + f(6) = 2.348
