enlargement inverse

[NotAbod]

we can find translation's and rotation's inverse
but is there enlargement inverse? or shear and stretch inverse?

Inverse of enlargement scale factor k is enlargement scale factor 1/k. The shape is smaller

but isn't there something like if factor is negative then it should be on the other side of center of enlargement ? or in case of stretch / shear in another quadrant ?
