Answer each question by True or False. Justify your answer.

(1) True or False? The set V = {p ∈ P2: p (7) = 0, p’ (7) = 0} is a subspace of P2.

(2) True or False? The set of 2 by 2 matrices whose entries are either all 0 or all nonzero is a subspace of the set of all 2 by 2 matrices M2×2(R).

(3) True or False? The set of all functions in C([0, 1]) such that f(0) = f( 1 /3 ) = f( 2 /3 ) = f(1) = 0 is a subspace. Note: C([0, 1]) is the set of continuous functions on [0,1].

(4) True or False? For an m × n matrix A, the null space is always a subspace of Rn.

(5) True or False? The set of all solutions to the ODE y’’ + 2y’ 0 +y = 3e^x forms a vector space.

(6) True or False? The ODE y’’ +2y’ +y = cos(e^x −7)+ sec(x) can be solved using the technique of undetermined coefficients.
