How to verify the rank-nullity theorem for the linear application $frac{d}{dx}in...
$begingroup$
I know that the rank-nullity theorem states that let $T: Vrightarrow W$ be a linear transformation, then:
$$ operatorname{Rank}(T)+ operatorname{Nullity}(T)=dim(V)$$
But since $frac{d}{dx}in operatorname{End}(mathbb{K}[x]_2)$ is also a linear transformation, I want to verify the rank-nullity theorem with this particular situation.

What exactly do you mean by $Bbb K[x]_2$?

Clarification question, is $mathbb{K}[x]_2$ the ring of polynomials of $mathbb{K}$ localized at the ideal $2$ or is $mathbb{K}$ the field with 2 elements?

$mathbb{K}[x]_2$ is the ring of polynomials of 𝕂 localized at the ideal 2 $(ax^2+bx+c)$

You can just take a proof of the abstract theorem and then substitute everything there with your example.
