L: R^2=>R^2 is defined by L(x,y)= (x+2y), (2x-y) let S be the natural basis for R^2 and T=(-1,2), (2,0). T is another basis for R^2. Find the matrix representing L with respect to A) S B) S and T C) T and S D) T E) Compute L L(1,2) using the definition of L and also the matrices obtained in a,b,c,d. I am pretty lost here. I plugged in 1,0 0,1 for the natural basis, solving for part A. plugged in T=(-1,2), (2,0) to solve for part C. Is this correct? Any ideas on the rest?
