I desperately need someones help with this question.
( please do not just say what do you think).I don't feel confident in subspaces yet.thanks.
F is a vector space of functions from R to R, with the usual operations of addition and scalar multiplication of functions. For the subset below of F, write down two functions that belong to the subset and determine whether or not the subset is a vector subspace of F.
The set of polynomials whose coefficients are all non-negative.
