1Hint: Use the theorem from class that any linearly independent
list of vectors is contained in a basis
2Hint: Remember that we prove the equality of sets X = Y by
showing X ⊂ Y and Y ⊂ X.

Exercise 6.8.12. Determine if the following statements are true or false. If a statement is true, prove it. If a statement is false, give a counterexample or some other proof showing it is false. Unless otherwise specified, let V and W be a finite-dimensional vector space over field F, let (v1, ..., Un} be a basis of V, let {1,...,n} be a subset of W (possibly with repeated vectors), and let 6: V W be the...
