Matrix A2= [1 2 3; 4 5 6; 7 8 9; 3 2 4; 6 5 4; 9 8 7] 1. Find a basis for the range of the linear transformation defined by A2. (*TA2 is defined to be a linear transformation which maps any vector x to A2 * x. That is TA2 = A2 * x. Also the range of the Linear transformation represented by A2 is the same as the column space of A2.)
2. Find a basis for the nul TA2)
3. Find rank (TA2)
