2.1 (a) Demonstrate all 10 conditions and conclude it is a vector space.
threshold: pts
 5.0 to >4.0 pts All 10 conditions clearly demonstrated. blank 4.0 to >3.0 pts All 10 conditions demonstrated, with some minor logical errors. _4029 3.0 to >2.0 pts Major logical errors for a few of the conditions _4467 2.0 to >1.0 pts Did not correctly identify as a vector space, but made some effort to explain reasoning or vey little explanation given even if correctly identified as a vector space. _1502 1.0 to >0.0 pts Did not correctly identify as a vector space with little reasoning or correctly identified as a vector space with no explanation. _6595 0.0 to >0 pts No Marks blank_2

2.1 (b) Demonstrate that it is not a vector space by showing one of ten conditions is not satisfied.
threshold: pts
 2.0 to >1.0 pts Correctly provided example of how one of the conditions is not satisfied _2337 1.0 to >0.0 pts Logical error in example but correctly identified as not a vector space. _1447 0.0 to >0 pts Identified the set as having satisfied all 10 conditions _500
