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];
