The image space of a linear transformation T:V → W is the set of vectors such that

$\text{Im(T)} = \{ A \vec{v} |A \vec{v} \in W \}$

Given the n×n transformation matrix A, the image space of the transformation will be identical to the column space of A. Therefore, because of the rank–nullity theorem,

$n = \text{dim(im(A))} + \text{dim(null(A))}$

The image space of an invertable (that is, the determinant is not zero) n×n matrix is Rn.
