Show if A = If so, find the DA. 6. (10 points). Show if R² --> R³ such such that L(x, y) = (x, x+y, x-y) is a linear transformation. 6. (20 points). Supposed that R2 --> R³ such such that L(x, y) = (x, x+y, x-y) be a linear transformation. Find the ker(L), range(L) and show if the L is one-one, onto.
