Select the correct answer from each drop-down menu.

The given table shows the values of p(x), which represents the number of cars in store parking lot when the store has been open for x hours.



x 0 2 4 5 6 8 10

p(x) 2 17 24 30 24 17 2

According to the table, function p is symmetric about x =

. This means that the same number of cars can be expected in the parking lot when the store has been open for 3 hours as when it has been open for
