#13

In Problems 9 21, determine whether the given set of vectors forms a basis for the specified vector space. IR 12 IR 5'8 13 0 16 IR 0 15 IR3 18 17 IR 19 IR

Answer 1

{[3 -1], [-1 2], [-1 1], R^3 not a basis because [3 -1] not belongsto R^3 do not form basis we can not talk about R^3 actually I think this is null point, in R^2, it does not form a basis because in R^2 only. Vector in this basis so it does not form a basis of R^3
