What is a function in Excel?

A special keyword used to process data

The correct answer is option 1- A special keyword used to process data.

A function is a special key word which can be entered into a cell in order to perform and process the data which is appended within brackets. There is a function button on the formula toolbar (fx) when we click with the mouse on it; a function offers assistance and useful prompts into a spreadsheet cell. Alternatively we can enter the function directly into the formula bar. A function involves four main issues:

• Name of the function
• The purpose of the function
• The function needs what argument(s) in order to carry its assignment.
• The result of the function.
