10. Mark the following statements true or false. If false, give an explanation of why it
is false.
(a) R² is a subspace of R³.
(b) The column space of A is the range of the mapping x → Ax.
(c) The kernel of a linear transformation is a vector space.
(d) A single vector by itself is linearly dependent.
(e) If H=Span{bị, ..., b,}, then {bị, .., b,} is a basis for H.
(f) The columns of an invertible n x n matrix form a basis for R".
(g) If f is a function in the vector space V of all real-valued functions on R and if
f(t) = 0 for some t, then f is the zero vector in V.
(h) If a finite set S of nonzero vectors spans a vector space V, then some subset
of S is a basis for V.
