Let T be a linear transformation from R^3 to R^3 Determine whether or not T is one-to-one in each of the following situations:.
1. Suppose T(0, -2, -4) = u. T(-3,-4,1) = v. T(-3, -5, -3) = u + v.
2. Suppose T(a) = u, T(b) = v. T(c) = u + v. where a, b,c, u,v v are vectors in R^3
3. Suppose T is an onto function
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
