Hi..what is the meaning of F: R(m)-> R(n)......

[Granpa Simpson]

m is a set and n is a set..and it means a function whose domain is m and range is n...!!!!

[Akshay Jain]

It means that the function F maps the points from the real space R with dimention m (domain of the function) to the points in real space with n dimention (range of the function)
