The function that can be used to give a total of the returned rows is the ROLL UP function. This function is used in SQL to create subtotals and grand totals in the result set. However, please note that the question seems to be a bit unclear as none of the functions listed directly give a total of returned rows.

Here's a step by step guide on how to use ROLL UP:

1. Start by writing your SELECT statement. For example, if you have a table named 'Orders' and you want to get the total quantity of each product sold, you would write: SELECT Product, SUM(Quantity) FROM Orders.

2. After the FROM clause, add a GROUP BY clause that specifies the column that you want to aggregate. In this case, it would be the 'Product' column: GROUP BY Product.

3. Finally, to get the total quantity of all products sold, add WITH ROLLUP at the end of the statement: SELECT Product, SUM(Quantity) FROM Orders GROUP BY Product WITH ROLLUP.

This will return a result set that includes a row for each product, as well as a final row that gives the total quantity for all products.
