Question

For the following transformation T either

• give its standard matrix (i.e. the matrix relative to thestandard bases of the domain of T and the codomain of T), if T islinear, or

û Enter your answer as follows. Take care to read theseinstructions; the usual type/syntax checking is not possible with"matrix" entries. So type/syntax errors will attractpenalties.

• If T is linear enter the entries ofits standard matrix starting at the cell in the top lefthandcorner, and leave any cells you don't needempty.
• Similarly, to enter a counter-example of L2enter a scalar k and three vectors
  k   v    T(kv)     k T(v) in that order in the 4 cells of the top row of thetable, leaving all other cells empty. To be acounter-example of L2, you musthave

  separate the entries by commas and enclose inc( ), e.g. c(1, 2 ,3) representsthe column vector

Explanation / Answer

one of the components of the range vector is z-5. 5 is of degree 0 . that means it is not linear. one of the components of the range vector is not linear. that means T is not a linear transformation. so, no question of finding the matrix. T æ
