Problem 2. (a) Provide examples of the following or explain why it is not possible: e a set of 3 vectors that spans R*; e a set of 4 vectors that spans R*; e a set of 4 vectors that does not span R*; e a set of 5 vectors that spans R* (b) For each of the sets you provided that do span R*, are any of the vectors a linear combination of the others in your set? () Based on your results, formulate a conjecture about how a set of n 1,n,n + 1 vectors would or would not span R&quot
