1. The problem statement, all variables and given/known data i) Find the Image and Kernel of A = (2,1)(-4,-2) (where each bracket is a row). ii) Calculate A2 and use i) to explain your result. 2. Relevant equations None 3. The attempt at a solution So I can do everything up to the very last bit (i think anyway). i) The Kernel = (1,-2) = Image. ii) A2 = 0 but this is where I don't know what to say. How do I use part i) to explain the 0 matrix found?
