The graph of the function , f(x)=a*x^4+b*x^3+c*x^2+d*x+e, passes through the points (-3, 6.8), (-1.5, 15.2), (0.5, 14.5), (2, -21.2), and (5, 10). Write a script that will prompt for the ordered pairs as inputs and solve five equations with the five unknown constants: a, b, c, d, and e. You need to set up a matrix equation and solve for the unknowns by first finding the inverse of a matrix. Solve the system: y = X * h, for h

Since this is homework, partial answer is given, You have to start with the following :

     X=[(-3)^4     (3)^3       (3)^2      3      1;
       (-1.5)^4   (-1.5)^3    (-1.5)^2   (-1.5) 1;
       (0.5)^4    (0.5)^3     (0.5)^2    (0.5)  1;
       (2)^4      (2)^3       (2)^2      2      1;
       (5)^4      (5)^3       (5)^2      5      1];
