WebSOLUTION: If m > n and we have the maximum number of pivots (n of them), then every column is a pivot column. This means that the equation Ax = b has at most one solution for every b. That means the mapping x !Ax could be 1 1 (it is possible, but not necessary). On the other hand, if we have the maximum number of pivots, we would still not have
