Exercises 31 and 32 reveal an important connection between lin-
ear independence and linear transformations and provide practice
using the definition of linear dependence. Let V and W be
vector spaces, let T: V W be a linear transformation, and let
{V1,..., Vp} be a subset of V.

31. Show that if {V1,...,V,} is linearly dependent in V, then
the set of images, {T(v),...,T(v,)}, is linearly depen-
dent in W. This fact shows that if a linear transforma-
V1 =
tion maps a set {V1,...,Vp} onto a linearly independent set
{T(v)), ... T(vp}}, then the original set is linearly indepen-
dent, too (because it cannot be linearly dependent).

32. Suppose that T is a one-to-one transformation, so that an
equation T(u) = T(v) always implies u v. Show that if
the set of images {T(v),..., T(v,)} is linearly dependent,
then {v,..., vp} is linearly dependent. This fact shows that
a one-to-one linear transformation maps a linearly indepen-
dent set onto a linearly independent set (because in this case
the set of images cannot be linearly dependent).
