                    Notes          Writing the inverse, we have





                                   which is a function.

                                   Let us consider some examples from daily life.
                                                            : Student   Score in Mathematics
                                              –1
                                   Do you think   will exist?
                                                                                                –1
                                   It may or may not be because the moment two students have the same score   will cease to be a

                                   function. Because the first element in two or more ordered pairs will be the same. So we conclude
                                   that
                                                             every function is not invertible.
