2 Determine if the set W = {(a, b, ab): where a and b are non – zero real numbers} is a subspace of R3. If it is prove it, if it does not show which vector space axiom fails.
Determine which of the following sets are subspaces of the given vector space. If it is NOT a subspace, circle NO and give a property that fails. Circle YES if it is a subspace, but you do NOT have to prove it. Let a and b be real numbers. a a+b (b) Let S= 1 . Is S a subspace of R3? YES or NO (c) Let S = {p(t) |p(t) = at + bt}. Is S a subspace of...

6. Let W be the set of all vectors of the form W {(a,b,c): a – 2b + 4z = 0} Is W a subspace of the vector space V = R3?
Determine whether the set w is a subspace of R3 with the standard operations. If not, state why. (Select all that apply.) W = {(x1, 1/X1, X3): X1 and xy are real numbers, X1 + 0) W is a subspace of R W is not a subspace of R because it is not closed under addition. Wis not a subspace of R because it is not closed under scalar multiplication. X
Determine if the set V = {at? | a € R} is a subspace of the vector space P2 = {ao +ajt + azt? | ao, a1, az ER}. You may assume that vector addition in P2 is given by the usual addition of polynomials and that the scalars used in scalar multiplication are real numbers. If you decide that Vis a subspace of P2, then identify the zero vector in V and explain briefly why Vis closed under vector...
Can u please answer the question (G) 1. (15 marks total) Consider the real vector space (IR3, +,-) and let W be the subset of R3 consisting of all elements (z, y, z) of R3 for which z t y-z = 0. (Although you do not need to show this, W is a vector subspace of R3, and therefore is itsclf a rcal vector space.) Consider the following vectors in W V2 (0,2,2) V (0,0,0) (a) (2 marks) Determine whether...
