numerical analysis question

3) Use your code to interpolate the data using cubic splines for function y = (1+4x2)-1 (the function is known as the "Witch of Agnesi" or "Runge" function, where the points are obtained by dividing the interval for the independent variable [-5,5) into 20 intervals of equal length. Plot the original function on (-5,5) along with the splines. Provide a write-up with the results.
