- can a subspace of R^n have a dimension less than n.arrow_forwardLet P2P2 be the vector space of all polynomials of degree 2 or less, and let HH be the subspace spanned by 4x2+11x−8, x2+4x−34x2+11x−8, x2+4x−3 and 4−5x4−5x. The dimension of the subspace HH is . Is {4x2+11x−8,x2+4x−3,4−5x}{4x2+11x−8,x2+4x−3,4−5x} a basis for P2P2? Be sure you can explain and justify your answer. A basis for the subspace HH is {{ }}. Enter a polynomial or a comma separated list of polynomials, where you can enter xx in place of x2x2.arrow_forwardProve or disprove: If P4 is the vector space of polynomials of degree 4 or less, then the set of all even degree polynomials in P4 form a subspace of P4.arrow_forward
