Correct answer & explanation

✓

AddDays(Today(), 7)

The AddDays function in Power Apps (Power Fx) uses the syntax AddDays(DateTime, NumberOfDays). So AddDays(Today(), 7) returns the date 7 days from today. Option A uses a semicolon and has the arguments reversed. Option C also reverses the arguments (days first, then date). Option D uses a string for the number of days, which is invalid.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
AddDays(7; Today())
Why it's wrong here
Incorrect. Uses a semicolon instead of a comma, and arguments are reversed (date should be first).
✓
AddDays(Today(), 7)
Why this is correct
AddDays accepts a date and a number of days, returning that date offset forward. Passing Today() with 7 yields the date one week from now, matching the stem's requirement exactly; the function's argument order is date first, increment second.
✗
AddDays(7, Today())
Why it's wrong here
AddDays takes the date first and the day count second, so this reverses the arguments and passes a number where a date is expected. It is tempting because the intent — adding seven days to today — is right, and AddDays is genuinely the correct function for date arithmetic; only the parameter order is wrong.
✗
AddDays('7', Today())
Why it's wrong here
AddDays expects a datetime value first and a number of days second, so passing '7' as the datetime and Today() as the count reverses the arguments and fails. It is tempting because AddDays is genuinely the function that offsets a date, and would be correct with the arguments in the documented order.
