Final answer:
The EOMONTH function indeed returns the serial number of the last day of the month for a specified number of months before or after a starting date, which makes the statement true.
Step-by-step explanation:
The statement that the EOMONTH function returns the serial number of the last day of the month a specified number of months from a given date is true. In spreadsheet programs like Microsoft Excel, the EOMONTH function is used to calculate the date that is the last day of a month which falls a specific number of months before or after another date. For example, if you want to know what the last day of the month is six months after March 15, 2023, you would use the EOMONTH function with the start date as March 15, 2023, and the month argument as 6.
