b. (f o g)(4), (f o g)(2), (f o g)(-2) (f o h)(-1),(h o g)(3)


A., (f o g)(x) = f(g(x)), = 3221ax – 1, =221a3\xd7\xb2+2-1, =221a3\xd7\xb2+1, b., =3221a4-1, = 3.2 – 1, = 5, =3221a2-1, (f o g)(-2) = f(g(-2)), =3221a-2-1, = tidak ada jawaban karena tidak ada hasil akar dari angka < 0, =3(-1)\xb2+2-1, = 3 + 2 -1, = 4, =(, \xb2+2, = 3 + 2, = 5
