When no function is given, you can determine preimages by using the definition of a preimage. A preimage of a set under a function is the set of all elements in the domain that map to the given set. So, you would need to find all elements in the domain that map to the given set, even if the function itself is not explicitly defined. This may involve using the properties or characteristics of the given set to determine its preimage. **

The Jacobian matrix being surjective means that it has full rank, which implies that it is onto. If the Jacobian matrix has exactly 3 preimages for each point, it means that the function is locally 3-to-1. However, the surjectivity of the Jacobian matrix does not necessarily guarantee that there are exactly 3 preimages for each point. It is possible for the Jacobian matrix to be surjective and have a different number of preimages for each point. **

The Jacobian matrix being surjective means that its rank is equal to the dimension of the target space. If the Jacobian matrix has exactly 3 preimages for every point, it implies that the function is locally 3-to-1. Whether the Jacobian matrix is surjective and has exactly 3 preimages for every point depends on the specific function being considered. It is possible for a function to have a surjective Jacobian matrix and 3 preimages for every point, but it is not a general rule. **
