1. The problem statement, all variables and given/known data State that is either true or false The span of an empty set is empty set 2. Relevant equations n/a 3. The attempt at a solution from definition, when you span a subset of vector space, the subset must be non-empty. so, how should i answer this question? should i answer "true"? since the premises is undefined, so either the consequence is true or false, the statement is still true. is that correct?
