1. The problem statement, all variables and given/known data let a be the vector [2,3,1] in R3 and let T:R3-->R3 be the map given by T(x) =(ax)a State with reasons, the rank and nullity of T 2. Relevant equations 3. The attempt at a solution Im having trouble understanding this... I know how to do this with a matrix ie row reduce and no. of leading cols = rank ,, and then no. of non leading cols = nullity. But im stuck on how to go about it with this eqn.? And that the rank = dim(image) but how would I finad that... or alternatively the dim(kernal)? Thanks.
