True or False? In Exercises 49 and 50, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text.
(a) To show that a set is not a
(b) The set of all first-degree polynomials with the standard operations is a vector space.
(c) The set of all pairs of real numbers of the form

- Let V be the set of all positive real numbers. Determine whether V is a vector space with the operations shown below. x+y=xyAddition cx=xcScalar multiplication If it is, verify each vector space axiom; if it is not, state all vector space axioms that fail.arrow_forwardProofProve in full detail that M2,2, with the standard operations, is a vector space.arrow_forward13. Finish verifying that is a vector space (see Example 6.4).arrow_forward
- Determining Whether a Set Is a Basis In Exercises 35-38, determine whether the set {v1,v2}is a basis for R2.arrow_forwardLet v1, v2, and v3 be three linearly independent vectors in a vector space V. Is the set {v12v2,2v23v3,3v3v1} linearly dependent or linearly independent? Explain.arrow_forwardTesting for a Vector Space In Exercises 13-36, determine whether the set, together with the standard operations, is a vector space. If it is not, identify at least one of the ten vector space axioms that fails. M4,6arrow_forward
- Does the empty set form a vector space?arrow_forwardGive an example of a space is not vector space.arrow_forwardDetemine whether the set, M,, with the standard operations, is a vector space. Ifit is not, then detemine the set of axioms that it fails. This set is not a vector space. It fails the following axioms. Commutative property Additive identity Distributive property b) a) This set is not a vector space. It fails the following axioms. Scalaridentity Associative property Distibutive property Additive identity c) This set is a vector space. All ten vector space axioms hold. This set is not a vector space. It fails the following axioms. d) Additive identity Additive inverse Associative property Scalaridentityarrow_forward
