For the following, V and W are finite dimensional vector spaces (over F) and T is a function from V into W. a) If T is linear than T preserves sums and scalar products . b) If T(x+y)= T(x)+T(y), then T is linear. c) T is one to one if and only if N(T)={0}. d) If T is linear then T(0v)=0w. e) If T is linear than nullity (T) + rank (T)=dim (W). f) If T is linear, then T carries linearly independent subsets of V onto linearly independent subsets of W. g) If T, U:V→ are both linear and agree on a basis of V, then T=U. h) Given x1, x2 ϵ V and y1, y2 ϵ W, there exists a linear transformation T:V→W such that T(x1)=y1 and T(x2)=y2.
