(1 point) Let T be a linear transformation from R3 to R3 . Determine whether or not T is one-to-one in each of the following situations: B 1. Suppose T(a)=u, T(b)=v, T(c)=u+v, where a, b,c, u,v are vectors in R3. C 2. Suppose T is an onto function A 3. Suppose T(−1,−1,−3)=u, T(0,−2,3)=v, T(−1,−2,0)=u+v. A. T is not a one-to-one function B. T is a one-to-one function C. There is not enough information to tell
