Which function would be used to return only the first two items of a list?

The function that is used to return only the first two items of a list is LISTLEFT. This function specifically allows you to extract a specified number of items from the beginning (or left side) of a list. When you call LISTLEFT with a list and a count of two, it outputs a new list containing just the first two elements.

In contrast, LISTCOUNT is utilized to return the total number of items in a list, which does not provide any elements but rather just the count. LISTINDEXOF is meant for finding the index of a specific item in the list, and it also does not manipulate or return multiple items. Lastly, LISTGETWITHDEFAULT retrieves an item from a list at a specified index but does not inherently limit the return to just the first two items.

Thus, LISTLEFT is the appropriate choice for extracting the first two items from a list, aligning perfectly with the requirement of the question.
