Latihan Soal;

Di Ketahui : f(x)=x²-4 dan g(x)=-4x+1

Di Tanya :
1.(f ° g)(x)
2.(g ° f)(x)
3.(f ° f)(x)
4.(g ° g)(x)

Tolong Di Bantu Kak

Note;

#Pake Cara oke
#Jangan Ngasal​​​​ 1. (f⁰g(x)) = f(-4x+1)
= (-4x+1)² - 4
= 16x²-8x+1-4
= 16x -8x-3
2. (g⁰f(x))= g(x²-4)
= -4(x²-4)+1
= -4x²+16+1
= -4x+17
3. (f⁰f(x))= f(x²-4)
= (x²-4)²-4
= x⁴-8x²+16-4
= x⁴-8x²+12
4.(g⁰g(x))= g(-4x+1)
= -4(-4x+1)+1
= 16x-4+1
= 16x-3
