For problems 1 to 3 Let T: R2 †’ R2 be the linear transformation given by T( ) = A, where

1. verify that

and explain why this means that the x-axis is mapped onto itself.
2. Verify that

and explain why this means that the y-axis is mapped onto the line y = x/2.
3. Verify that

and use this fact to give a geometric interpretation of the mapping.
