17

Step-by-step explanation:

White point: count the valuations of f(x) until x = 4.

If x = 4, y is not count.

Black point: count the valuations of f(x) = 4 or more.

If x = 4, y = 17

I hope I've helped you.

And sorry about my English.

6 +6 =12

Step-by-step explanation:

it is telling you that the statement is true because the next equation says 6 +6 -n and the first equation helps you know the answer is true because you know that n is being taken away from the answer which is 12.

hope that helps and makes sense
