A fourth-order polynomial passes through the five points for which the independent and dependent variables, x and y, respectfully, are given (-2,37), (-1,7), (0,5),(1,13), and (2,61). Find the polynomial by any suitable method. Here, x represents the spatial location and y the species concentration in chemical reactor.
