(Recall that the dimension of a vector space V (dimV) is the number of elements in a basis of V.) DEFINITION 1.1 (Linear transformation) Given vector spaces Uand V, T: U7!V is a linear transformation (LT) if If they are, prove it; if not, provide a counterexample to one of the properties: (a) T : R2!R2, with T x y = x+ y y Solution: This IS a linear transformation 441, 443) Let L : V W be a linear transformation. $$ $$ + ck+1vk+1 + + cnvn, w = L(v) = L(c1v1
This means that the null space of A is not the zero space. Hence \(f\) is surjective, so every element \(t \in T\) has at least one pre-image.

Example 0.6. }\), $$f(0_{V})=0_{W}.$$ In review exercise 3, you will show that a linear transformation is one-to-one if and only if \(0_{V}\) is the only vector that is sent to \(0_{W}\): In contrast to arbitrary functions between sets, by looking at just one (very special) vector, we can figure out whether \(f\) is one-to-one! Sierra Club Foundation Board, Then we can find \(v_{1} \neq v_{2}\) such that \(Lv_{1}=Lv_{2}\). in V with L(v)
