f(x) = x! + 14x × 4
f(5) =​

Answer 1

Penjelasan dengan langkah-langkah:

f(x) = x! + 14x × 4

f(5) = 5! + 14x × 4

f(5) = (5 × 4 × 3 × 2 × 1) + 14x × 4

f(5) = (20 × 3 × 2 × 1) + 14x × 4

f(5) = (60 × 2 × 1) + 14x × 4

f(5) = (120 × 1) + 14x × 4

f(5) = 120 + 14x × 4

f(5) = 120 + 14(5) × 4

f(5) = 120 + (14 × 5) × 4

f(5) = 120 + 70 × 4

f(5) = 120 + 280

f(5) = 400

Answer 2

Penjelasan dengan langkah-langkah:

f(x) = x! + 14x × 4

f(5) = 5! + 14(5) × 4

f(5) = (5.4.3.2.1) + 14(5) × 4

f(5) = (20.3.2.1) + 14(5) × 4

f(5) = (60.2.1) + 14(5) × 4

f(5) = (120.1) + 14(5) × 4

f(5) = 120 + (14.5) × 4

f(5) = 120 + 70 × 4

f(5) = 120 + 280

f(5) = 400
