Let $a\in R$ and $W={f\in P_{n}(R):f(a)=0}$ be a subspace of $P_{n}(R)$ . Find $dim(W)$ .

There are several approaches to this problem.

Approach 1: Use Isomorphisms

Approach 2: Use the Rank-Nullity Theorem

Approach 3: Find a Basis by Decomposing the Polynomial

Approach 4: Find a Basis of without Decomposing the Polynomial
