Penjelasan dengan langkah–langkah:

(BA untuk kak tnov)

(a o b o c o d)(x)

= a(b(c(d(x))))

= a(b(c(x³)))

= a(b(9+4x³))

= a(2(9+4x³)+8))

= a(18+8x³+8)

= a(8x³+26)

= (8x³+26)²-5

= 64x⁶+416x³+676-5

= 64x⁶+416x³+671

tur. pertama= 384x⁵+1248x²

tur. ked = 1920x⁴ + 2496x

ketiga. = 7680x³+2496

keempat. = 23040x²

kelima. 46080x

keenam= 46080

Komposisi Fungsi

a(x) = x² – 5

b(x) = 2x + 8

c(x) = 9 + 4x

d(x) = x³

(a°b°c°d)(x)

= (a°b°)(9 + 4x³)

= a(2(9 + 4x³) + 8))

= a(8x³ + 26)

= (8x³ + 26)² – 5

y = (8x³ + 26)² – 5

y = 64x⁶ + 416x³ + 671

y'''''''

= 6! 64 + 0

= 46080
