1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution In the previous problem I was asked to identify if a polynomial, such as f(x)=2x was a linear transformation. In that case I checked to see if f(ax + by) = f(ax) + f(by). I figure I would be doing something similar in this case. I would check to see if T(ax + by) = T(ax) + T(by). So for problem (A) would I do something like: and since T(ax + by) ≠ T(ax) + T(by), T1 is not a linear transformation?
