f(z) = 70z × z! + 200 – z²
f(3) = 70(3) × 3! + 200 – 3²
f(3) = 210 × 3! + 200 – 3²
f(3) = 210 × 6 + 200 – 3²
f(3) = 210 × 6 + 200 – 9
f(3) = 1.260 + 200 – 9
f(3) = 1.460 – 9
f(3) = 1.451

f(z) = 70z × z! + 200 – z²
f(3) = … 1.451
Penjelasan dengan langkah-langkah:
f(z) = 70z × z! + 200 – z²
f(3) = 70(3) × 3! + 200 – 3^2
f(3) = (70×3) × (3×2×1) + 200 – (3×3)
f(3) = 210 × (6×1) + 200 – 9
f(3) = 210 × 6 + 200 – 9
f(3) = 1.260 + 200 – 9
f(3) = 1.460 – 9
f(3)= 1.451
