(1 point) NOTE: In this question, you probably want to answer part a last parts b and c are meant to justify the answer to part a. Let 1P2 be the vector space of all polynomials of degreez or less: and letr be the subspace spanned by 4.132 3:3 + 2, 12.1: 3932 16 and 7:32 3.1: + 3. a. The dimension of the subspace H is b. Is {49:2 35: + 2, 12: 39:32 16, 79:2 3:]: + 3} a basis for 132'? Be sure you can explain and justify your answer. C. A basis forthe SUDSDEICE H iS { }. Enter a polynomial or a comma separated \"51 of polynomials
