3. Consider the function f(2 E [, we want to interpolate this function on for 25a2+1" 1,2,3, .,n +1, which are n + 1 equally spaced points on the interval [-1, 1. Use the MATLAB func- tion LagrangeForm you wrote in problem 2 to plot the interpolating polynomial for n 5 and n 9. Show these two curves as well as the curve for f(x) in the same graph and distinguish them with legend. Do the interpolation polynomials match the function well
