# Math Help - Linear transformation question

1. ## Linear transformation question

I am having problem with this question

T: P2 --->R^2 T(a+bx+cx^2)=(a,b)

Find the basis for the kernel T and basis for the image T

according to the text book Kernel = { T(v)= 0 }, so the kernel should look like

T (a+bx+cx^2)=(0,0)

how exactly do you find the basis?

As for the image, up to my understanding, is it the entire vector space of P2 map into a subspace of R^2?

Come on. Let $(a,b)\in\mathbb{R}^2$ be arbitrary.What is $T(a+bx)$? Also, $T(a+bx+cx^2)=(a,b)=0\implies a=b=0$
