A third-order polynomial of the form y = Ax³ + Bx² + Cx + D is to be fitted to four time-velocity data points. At time x = 0, 1,
2, and 3 s, the velocity is measured as 7, 14, 29, and 58 m/s.
Using Gauss-Jordan elimination, find the curve that passes through these points. Also, solve the problem by employing the backslash operator in MATLAB and compare the results with those obtained earlier.
