Best ResponseYou've already chosen the best response.1Well your transformation matrix should be \[\left(\begin{matrix}1 & 0 & 2 \\ 0 & 0 & 0 \\ 1 & 1 & 0 \\ 0 & 1 & 1 \end{matrix}\right)\] check to make sure you see why.

Best ResponseYou've already chosen the best response.1Works for us... it should be dw:1349109968192:dw

Best ResponseYou've already chosen the best response.0dw:1349110409182:dw then wat would be Im(T) and ker(T) if it like this?

Best ResponseYou've already chosen the best response.0Im(T)={+x^2;x^2x^3;2+x^3} is it gonna be this?

Best ResponseYou've already chosen the best response.1The image is the set of all vectors y that you could get by applying the transformation T. The three columns of that matrix are linearly independent, which means that there is no nontrivial nullspace. However, because there are more rows than columns, the image cannot span all of P^4. Obviously the transformation will never yield a quadratic term because none of the columns have a nonzero entry in the second row. So the image would be something like all polynomials of degree <=4 of the form a + bx + cx^3

Best ResponseYou've already chosen the best response.1Oh I made a little mistake... it should be that there'll be no linear term, not quadratic. So the image will be the set of all polynomials of the form a + bx^2 + cx^3

Best ResponseYou've already chosen the best response.0ok, then the kernel =0 or what?

Best ResponseYou've already chosen the best response.0do i write zero or is the any way to represent empty for the kernel?

Best ResponseYou've already chosen the best response.1You could just say \[ker(T) = \vec{0} \] or you could write that it's empty, or only the zero vector, or whatever you want I suppose.
