Problem 3. (Linear Transformation) Let T: R → R" be a linear transformation with standard matrix A, i.e., for any x € R" we have T(x) = Ax. (1) How many rows and columns are there for the matrix A? Explain your answer. (2) Show that {T(x) : x ≤ R} = {x₁α₁ + ... + £nªn : I1, ..., In R} where a,. an are the column vectors of the matrix A. (3) Show that T is one-to-one if and only if the column vectors of A are linearly independent.
