## Main Question or Discussion Point

Hey guys!

I am having a major brain problem today, with this problem.

L is a linear transform that maps L:P

As such that (a

I am trying to find the basis for the kernel and range.

I know that the standard basis for P

And the kernel is when L(u)=0, but I don't know how to find the transformation matrix, since we're not dealing with numbers in R, but in the set of polynomials. Is there another way to find the kernel/range and bases without using the T matrix?
