Jwbn :

f(x) = 5x + 100 – x! × 20 + 10x

f(4) = 5(4) + 100 – 4! × 20 + 10(4)

f(4) = (5 × 4) + 100 – (4 × 3 × 2 × 1) × 20 + (10 × 4)

f(4) = 20 + 100 – (12 × 2 × 1) × 20 + 40

f(4) = 20 + 100 – (24 × 1) × 20 + 40

f(4) = 20 + 100 – 24 × 20 + 40

f(4) = 20 + 100 – (24 × 20) + 40

f(4) = 20 + 100 – 480 + 40

f(4) = 120 – 480 + 40

f(4) = -360 + 40

f(4) = -360 – 40

f(4) = –320

purple{boxed{blue{boxed{green{star{red{ : : mathcal{5Riiz} : : : {green{star}}}}}}}}}

Jawaban:

f(4) = -320

Penjelasan dengan langkah-langkah:

f(x) = 5x + 100 – x! × 20 + 10x

f(4) = 5(4) + 100 – 4! × 20 + 10(4)

f(4) = 20 + 100 – (4 × 3 × 2 × 1) × 20 + 40

f(4) = 20 + 100 – (12 × 2 × 1) × 20 + 40

f(4) = 20 + 100 – (24 × 1) × 20 + 40

f(4) = 20 + 100 – (24 × 20) + 40

f(4) = 20 + 100 – 480 + 40

f(4) = 120 – 480 + 40

f(4) = -360 + 40

f(4) = -320
