Final answer:
When copying and pasting a formula in a spreadsheet, the formula will adjust automatically if it uses relative references, or remain the same if it uses absolute references. It overwrites any existing data in the destination cell without corrupting the formula.
Step-by-step explanation:
When you copy a formula from one cell to another in a spreadsheet, the behavior of the formula depends on the type of cell references it contains. If the formula uses relative cell references (without the $ symbol), it will adjust automatically to the new location when pasted into cell D9. This is because relative references change based on the position where the formula is pasted. For example, if the formula in B2 is =A1+1 and you paste it into D9, it will automatically adjust to =C8+1. If the formula uses absolute cell references (with the $ symbol), such as =$A$1+1, then the formula will remain pointing to the same original cells even after pasting into D9.
The pasting of the formula into D9 will overwrite any existing data in D9, but it does not corrupt the formula or the spreadsheet. It simply replaces the previous content of D9 with the new formula.
