Suppose T:R4 R³ is the transformation induced by the following matrix A. Determine whether I is one-to-one and/or onto. If it is not one-to-one, show this by
providing two vectors that have the same image under T. If I is not onto, show this by providing a vector in R3 that is not in the range of T.
3 -3 -9 -3
A 3 -2 -6 -4
=
300-6
T is not one-to-one:
0
TO =
0
o and To 0
T is not onto:
o is not the image of any x under T.
