Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

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
Correct. Follows the proper Power Fx syntax: AddDays(DateTime, NumberOfDays) with Today() as the date and 7 as the number of days.
✗
AddDays(7, Today())
Why it's wrong here
Incorrect. Arguments are reversed: the number of days is provided as the first argument, but Power Fx expects the date first.
✗
AddDays('7', Today())
Why it's wrong here
Incorrect. The number of days is provided as a string ('7'), but AddDays expects a numeric value.
