Prove the following generalization of Theorem 2.6: Let V and W be vector spaces over a common field, and let ft be a basis for V. Then for any function f:ft>\N there exists exactly one linear transformation T: V -+ W such that T(x) = f(x) for all x ft.
ANSWER:Step 1 of 2
Given that V and W be vector spaces over a common field, say F and be a basis for V.
Let be an arbitrary function.
We consider .
Since be an arbitrary function and is a basis for V, there exists a linear transformation such that for all .
To prove that T is unique.
Let us consider an arbitrary element . Then,
