Vector u = (2, 2) is in W but its negative − … WebTo establish that A is a subspace of R2, it must be shown that A is closed under addition and scalar multiplication. If a counterexample to even one of these properties can be found, then the set is not a subspace. In the present case, it is very easy to find such a counterexample. isa day at the track https://helispherehelicopters.com
