If true explain why, if false provide a counterexample. 1. The set of polynomials {1, x² + 3x4, 2x² – 7x4} is a linearly independent set in P4. 2. For vectors v1, V2, V3 in a vector space V and scalar k e R, Span{v1, v2, V3} = Span{v1, kv2, V3}. 3. Let v1, v2, V3 be vectors in a vector space V. If {v1, v2, V3} is linearly dependent then {v1, V2} is linearly independent.arrow_forward
