Yes Ridhika dats a valid question..??infact i missed (1,1)..this will be common for all the sets..so by this logic it shud contain exactly two points, but not any other point except dat..because consider two curves y=(1/x^2) and y=(1/x^3)..except x=1, you cannot find any value for which the ordered pair will be same for both the curves..similarly if u consider for all the curves you will find the same..however according to my logic there will be exactly two points..!!!
