a. 21. Use zero-through third-order Taylor series expansion to predict f(3) for f(x) = 258 - 67 + 7x - 88 using a base point at x = 1. Compute the relative true error (%) and the relative approximate error (%) for each approximation. Do this by hand. Compute relative true error (%) and relative approximate error (%) as terms are added. Create a table that shows the order, calculated value of f(3), relative true error and relative approximate error. b. Write a MATLAB function to evaluate the Taylor series. Compute relative true error (%) and relative approximate error (%) as terms are added. Create a table that shows the order, calculated value of f(3), relative true error and relative approximate error
