present a plot of FS vs fS across the range of fS (, 0 fS 1) showing that this composition data are fitted by the copolymer composition equation with values rs=0.4 and rAN=0.04.

and if you were not given the rs and rAN values how would you fit the composition data to obtain these values (of rs and rAN)
