f(x) = 7x – x! – 12 + 2
f(2) = …
Q.
Jwb :
f(x) = 7x – x! – 12 + 2
f(2) = 7(2) – 2! – 12 + 2
f(2) = (7 × 2) – 2! – 12 + 2
f(2) = 14 – 2! – 12 + 2
f(2) = 14 – 2 × 1 – 12 + 2
f(2) = 14 – 2 – 12 + 2
f(2) = 12 – 12 + 2
f(2) = 0 + 2
f(2) = 2
2.
Penjelasan dengan langkah-langkah:
f(x) = 7x – x! – 12 + 2
f(2) = 7(2) – (2·1) – 12 + 2
f(2) = 14 – 2 – 12 + 2
f(2) = 12 – 12 + 2
f(2) = 0 + 2
f(2) = 2
