I'm dealing with isomorphisms, and I'm not quite sure of how to formulate this one. Mainly the elements from each function, so I can start to proof that is a linear and a bijective function. Here are the details:
If $V$ is the vector space of all polynomials of degree less than or equal to $n$, with coefficients in the field $K$. Proof that.
I'll be thankful if any help can be given.
