Let b1 = [1 - 3] and b2 = [2 - 5]. the set b = {b1, b2} is a basis for r2. let t : r2 rightarrow r2 is a linear transformation such that t(b1) = 4b1 + 4b2 and t(b2) = 8b1 + 5b2. then the matrix of t relative to the basis b is [t]b = [ ], and the matrix of t relative to the standard basis e for r2 is [t]e = [].
