Finding coefficients from 4 degree polynomial

I want to find unknown coefficients A,B,C,D,E from 4 degree polynomial equation "y=Ax^4+Bx^3+Cx^2+Dx+E". x and y are already given in table.

Read about polyfit. This will help you to fit the required degree polynomial and also gives you the coefficients. Also have a look on polyval.
