Very magnanimous of you to let f and g be defined that way. I certainly hope that they are satisfied with their lot in life. Now, did you have a question you wanted to ask? It would have been helpful had you taken the time to share your question rather than expect us to guess which of the many thousands of questions that could be asked about the information you gave. Before you post again, please read the instructions for posting that are given on the page where you actually make the post.
