3. Monomial least-squares (Coding Problem) (25 pts) In code, determine the least- squares estimation of a monomial of degree d using the n data [rk, yi] provided by the function yand computed with constant step in from -1 and +1. Plot and print out the points and fitting function for the following (n, d) pairs: (5,3), (10,3), (10.5). (This means you need to run your code with n = 5 and d = 3 and plot it, then run it again for n = 10 and d = 3 and plot that, etc.)
