f(x)=3x2-2x

f(x-2)=3(x-2)2-2(x-2)

          =3(x2-4x+4)-2x+4

          =3x2-12x+12-2x+4

          =3x2-14x+16

f(2x-1)=3(2x-1)2-2(2x-1)

            =3(4x2-4x+1)-4x+2

            =12x2-12x+3-4x+2

            =12x2-16x+5

4f(2x-1)=4(12x2-16x+5)

              =48x2-64x+20

f(2)=3(2)2-2(2)

      =3(4)-4

      =12-4

      =8

f(x-2)-4f(2x-1)+f(2)=(3x2-14x+16)-(48x2-64x+20)+(8)

                                  =-45x2+50x+4 

Jadi, jawabannya E
