Q. mth~

f(x) = x! + 2x - 18
f(5) = ...​

Jawaban:

~Fungsi

f(x) = x! + 2x - 18

f(5) = 5! + 2(5) - 18

f(5) = (5×4×3×2×1) + 10 - 18

f(5) = 120 + 10 - 18

f(5) = 130 - 18

f(5) = 112

f(x) = x! + 2x - 18

f(5) = 112

Pembahasan

f(x) = x! + 2x - 18

f(5) = 5! + 2(5) - 18

f(5) = (5 × 4 × 3 × 2 × 1) + (2 × 5) - 18

f(5) = (20 × 3 × 2 × 1) + 10 - 18

f(5) = (60 × 2 × 1) + 10 - 18

f(5) = (120 × 1) + 10 - 18

f(5) = 120 + 10 - 18

f(5) = 130 - 18

f(5) = 112
