_5.A third-order polynomial of the form y= Ax³+ Bx² + Cx + D is to befitted 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.
