Linear Algebra: Determine if this set is a vector space. Either show that the necessary properties are satisfied, or give an example showing that at least one of them is not. -The set P of all polynomials, with the usual definition of scalar multiplication, but with addition defined as polynomial multiplication (so f + g (warped addition) is equal to the product of f and g).

    In the second part of the answer, satellite said a(f+g) does not equal af + ag (all warped additon symbols).

    basically, the second rule is going to be f(+)g = f*g
