f(x) = 5! - 3x + 20
f(6) = ..?
f(x) = 5! - 3x + 20
f(6) = ..?
Penjelasan dengan langkah-langkah:
f(x) = 5! - 3x + 20
f(6) = 5! - 3(6) + 20
f(6) = (5 × 4 × 3 × 2 × 1) - (3 × 6) + 20
f(6) = 120 - 18 + 20
f(6) = 122
===============
f(6) = 122
Penjelasan dengan langkah-langkah:
- f(x) = 5! - 3x + 20
- f(6) = 5! - 3(6) + 20
- f(6) = (5.4.3.2.1) - 3(6) + 20
- f(6) = (20.3.2.1) - 3(6) + 20
- f(6) = (60.2.1) - 3(6) + 20
- f(6) = (120.1) - 3(6) + 20
- f(6) = 120 - (3.6) + 20
- f(6) = (120 - 18) + 20
- f(6) = 102 + 20
- f(6) = 122
