Homework Help: Need help understanding range of a linear tansformation

  1. Nov 11, 2007 #1
    I've been reading my book on finding the range of a linear transformation but cant understand it. Let's say:
    then the range(T)=columnSpace(A), right?

    But I've gotten confused so much about columnspaces b/c ive read many books and websites that explain it differently from each other. Can anybody explain to me in plain English how to find the columnspace(A) so I can find the range(T). Thanks in advance.
