ercise 6.2.2: Determining whether a subset of a vector space forms a subspace. info About Determine whether each subset of a vector space forms a subspace. (a) The subset W of Pn that contains all polynomials of degree n or less that have all negative coefficients. (b) The subset W=R+ of R where addition is defined as x+y=xy and scalar multiplication is defined as c⋅x=xc (c) The subset W of Rn×n for which the trace - the sum of the diagonal entries of a matrix - is zero. (d) The subset W of C[a, b] such that limx→x0f(x)=M where a
