It depends on your dictionary. This question is probably to see if you know how to use the dictionary. To find the answer, find the word notable in your dictionary and then you will see the guide words. The guide words are at the top of the page and show the first and last word on the page in order to guide you to your word.
In my dictionary, Webster's New World College Dictionary, Fourth Edition, "notable" is on the page with the guide words "Norwegian elkhound" and "note."
