Diketahui g(x)=×-4 dan (f°g)dan(x)=x²-3x+2.nilai f(0)sama dengan​

⃢ᴩᴇɴʏᴇʟᴇsᴀɪᴀɴ :

fog(x) = x² – 3x + 2

f(g(x)) = x² – 3x + 2

f(x-4) = x² – 3x + 2

⃢Keterangan :

X = a + 4

Jadi

f(a) = (a + 4)² – 3(a + 4) + 2

f(a) = a² + 8a + 16 – 3a – 12 + 2

f(a) = a² + 8a – 3a + 16 – 12 + 2

f(a) = a² + 5a + 6

______________________

f(x) = x² + 5x + 6

F(0) = 0² + 5.0 + 6

F(0) = 0 + 0 + 6

F(0) = 6
