Arrange the parabolas represented by the equations according to the positions of their foci on the coordinate plane, starting with the farthest left and ending with the farthest right.
a. y=(1)/(96)(x²+4x-1,628)
b. x=(1)/(32)(y²-8y-432)
c. x=-(1)/(52)(y²+18y-647)
c. x=-(1)/(28)(y²+12y-76)
e. x=-(1)/(8)(y²+2y+97)
f. y=(1)/(48)(x²+22x+73)
