Final Answer:
The two true statements regarding spreadsheet functions are:
Spreadsheet functions are predefined formulas that use values, referred to as arguments, to perform calculations.
Spreadsheet functions are case-sensitive.
Options 1 and 5 are the correct statements.
Step-by-step explanation:
Predefined Formulas: Spreadsheet functions are indeed predefined formulas designed to perform specific calculations. Users input values, known as arguments, into these functions to obtain calculated results.
Case Sensitivity: Spreadsheet functions are case-sensitive, meaning the function names must be entered with the correct letter case (e.g., "SUM" and "sum" may be interpreted differently).
Statements 2, 3, and 4 are false. A spreadsheet function does not begin with a hash sign (#), they are not primarily used to create tables and charts (option 3), and they are not exclusive to Microsoft Excel (option 4).
Options 1 and 5 are the correct statements.
