matematika kelas xi (koh) (x) =3-2x dan h(x)=2x-3/2-3x tentukan k(x)

koh (x) = (3 - 2x)
K(h(x)) = 3 - 2x
K((2x - 3)/(2 - 3x)) = 3 - 2x

Misal (2x - 3)/(2 - 3x) = a
2x - 3 = 2a - 3ax
2x + 3ax = 2a + 3
x(2 + 3a) = 2a + 3
x = (2a + 3)/(2 + 3a)

K(a) = 3 - 2((2a + 3)/(2 + 3a))
K(a) = 3 - (4a + 6)/(2 + 3a)
K(a) = 5a
K(x) = 5x
