224

Penjelasan dengan langkah-langkah:

Diketahui:

x = 8

Ditanya:

f(x) = 12x + x³ – x!! = … ?

Jawab:

f(x) = 12x + x³ – x!!
f(8) = 12(8) + 8³ – 8!!
f(8) = 12(8) + 8³ – (8.6.4.2)
f(8) = 12(8) + 8³ – (8.6.8)
f(8) = 12(8) + 8³ – (8.48)
f(8) = 12(8) + 8³ – 384
f(8) = 12(8) + (8.8.8) – 384
f(8) = 12(8) + (8.64) – 384
f(8) = 12(8) + 512 – 384
f(8) = (12.8) + 512 – 384
f(8) = 96 + 512 – 384
f(8) = 96 + (512 – 384)
f(8) = 96 + 128
f(8) = 224

Kesimpulan:

Jadi, f(x) = 12x + x³ – x!! adalah 224

SOAL 1

___________________________________________

f(x) = 12x + x³ – x!!

___________________________________________

f(8) = 12(8) + 8³ – 8!!

f(8) = (12.8) + (8.8.8) – (8.6.4.2)

f(8) = 96 + (64.8) – (48.4.2)

f(8) = 96 + 512 – (192.2)

f(8) = 96 + 512 – 384

f(8) = 96 + 128

f(8) = 224
