Exam #2 Solutions
... Since {T(b1), …, T(bn)} is linearly dependent, there exist real numbers c1, …, cn, not all zero, such that c1T(b1) + …+ cnT(bn) = 0. Thus, since T is a linear transformation, this implies that T(c1b1 + …+ cnbn) = 0. Now, since T is one-to-one, if T(x) = T(y), then x = y. We always have that T(0) = 0 ...
