Matrices for Linear Transformations. Let ß = {(−1, 4), (2, −1)} be a nonstandard basis for R² and Ɛ = {(1,0), (0, 1)} be the standard basis for R². [5pts.] Let T be the linear transformation T: R² → R² given by T(x, y) = (2y, x – 2y) Find [T], which is the matrix of T relative to the bases 3 and E.
