Suppose v1,,vmv_1,\dots,v_m is a list of vectors in VV. Define TL(Fn,V)T \in \mathcal L(\mathbf F^n, V) by

T(z1,,zm)=z1v1++zmvmT(z_1,\dots,z_m) = z_1v_1 + \dots + z_mv_m
  1. What property of TT corresponds to v1,,vmv_1,\dots,v_m spanning VV?
  2. What property of TT corresponds to v1,,vmv_1,\dots,v_m being linearly independent?

Note range T\text{range }T denotes the span of v1,,vmv_1,\dots,v_m and null T\text{null }T denotes all linear combinations giving zero

  1. TT being surjective, or equivalently range T=V\text{range }T = V
  2. TT being injective, or corresponds null T={0}\text{null }T = \{0\} (no combinations give zero)
