Please use the formula given in second figure below to solved for system of equations then when you get the coefficent you can plot the graph of parabola.

thank you thank you thank you so much

1. polyfit(), polyval() functions are not allowed to use in the MATLAB code.

2. Left division (\) and inv() function are not allowed to use in the MATLAB code.

3. To fit a curve with data, student may require to solve the system of equations. In case of solving

system of equations, students are free to apply Gauss elimination, LU decomposition, Jacobi

iterative method, or Gauss Seidel iterative method to solve the system of equations.
