Kak adek ada tugas tentang fungsi komposisi pertanyaan dari soal berikut tentukan: f(x)=x²+2 g(x)=x²+1 h(x)=x+1 1.(h°g°f) (x)= 2. (h°g°f) (-1)= 3. (f°g°h) (x)=

(hogof)(x)
= h(gof)
= (gof)+1
= ((x²+2)²+1)+1
= (x⁴+4x²+4+1)+1
= x⁴+4x²+6

(hogof)(-1)
= x⁴+4x²+6
= (-1)⁴+4(-1)²+6
= 11

(fogoh)(x)
= f(goh)
= (goh)²+2
= ((x+1)²+1)+2
= (x²+2x+1+1)+2
= x²+2x+4

(fogoh)(-2)
= x²+2x+4
= (-2)²+2(-2)+4
= 4-4+4
= 4
