1. The problem statement, all variables and given/known data Find a basis of the image im(LA) of the linear transformation LA: R^5 [tex]\rightarrow[/tex]R^3, x[tex]\mapsto[/tex]Ax where A = 1 -2 2 3 -1 -3 6 -1 1 -7 2 -4 5 8 -4 and hence determine the dimension of im(LA) 3. The attempt at a solution Using the equation LA= Ax, can i set up an augmented matrix of A and say, y1, y2 and y3 on the end? Then perform row reduction to get it into row reduced echelon form. Is that the right way to go about it? I will perform the calculation and update with it but any direction would be greatly appreciated.
