bon soon review question
lilb Can someone explain part b for this question. I don't get how the image and the kernel send all the vectors to 0
AshleyHoffman: June 5, 2015, 10:02 p.m. These were my notes from the review. I think it's because the kernel of a 1-1 matrix is 0 (and it's 1-1 if the im(T) = ker(T) ??), but I'm not sure at all. Even if this is wrong, hopefully it's a step in the right direction?
