QUESTION S 5. (1 point) Concept 5: Basis Determine which of the following sets could be a basis for P1. You should be able to do this by inspection. A = {1, x, x + 3} B = {3x - 1, x} C = {7+1} (a) Explain why the set you chose could be a basis and why the other sets would not be a basis. This can be justified using a short answer without calculation. (b) For the set that could be a basis show it satisfies the two conditions to be a basis. (If there are more than 1 set that could be a basis, just pick one)
