it's a matlab question. Please show the code:) thank you

Question #3-4 Marks The function e" can be approximated by its McLaurin series expansion as follows (note the alternating + and Alternatively, note that e-* - Thus, e-* can also be apporximated by 1 over the McLaurin series expansion of e". That is Approximate e-2 using both approaches above for n = 1, 2, 3, 4 and 5. Note, n is the degree of the polynomial not the number of terms. So here you use 2 terms, then 3 terms, ., and finally 6 terms. Compare each approximation to the true value of e20.135335 using the true relative error. What conclusions can you make about the two approaches
