Investigate the various functions that you find on the site.
Look for information about a function that interests you and that you did not already know. You need to find a function that some else has not covered. You may want to explore 1 or 2 functions before you begin your Discussion Board post.
After your research is complete, come back to the Discussion Board and post 1–2 functions that you found interesting.
Let me know if you need the link for the excel website.
