(.
Let H be the set of all points in the fourth quadrant in the plane V = R?. That is, H = {(x, y) | x > 0, y <0}. Is H a
subspace of the vector space V?
Is H nonempty?

Is H closed under addition? If it is, enter CLOSED. If it is not, enter two vectors in H whose sum is not in H, using a
comma separated list and syntax such as <1,2>, <3,4>.
Is H closed under scalar multiplication? If it is, enter CLOSED. If it is not, enter a scalar in R and a vector in H whose
product is not in H, using a comma separated list and syntax such as 2, <3,4>.
Is H a subspace of the vector space V? You should be able to justify your answer by writing a complete, coherent, and
