If the vector spaces are defined on the same scalar field, then yes.

Let $E=\{e_1,\ e_2,\ldots,\ e_n\}$ be a base of V and $F=\{f_1,\ f_2,\ldots,\ f_n\}$ be a base of W.

We can build the function

$T:V\mapsto W\quad f(e_i)=f_i$

We can extend T as one may imagine: every $v \in V$ can be written as a linear combination of elements in E:

$v = \displaystyle \sum_{i=1}^n \lambda_i e_i \implies f(v) = \sum_{i=1}^n \lambda_i f(e_i) = \sum_{i=1}^n \lambda_i f_i$
