Q1 4 Points In each part, determine if the given set H is a subspace of the given vector space V. Q1.1 1 Point V = R and H is the set of all vectors in R4 which have the form a b x= 1-2a for some scalars a, b. 1+3b 2 (e.g., the vector x = is an example of one element of H.) OH is a subspace of V. OH is not a subspace of V. Save Answer Q1.2 1 Point V = P3, the vector space of all polynomials whose degree is at most 3, and H = +³, 3t2}. OH is a subspace of V. OH is not a subspace of V.
