This one is also not well defined.
On first reading, it sounds as if several tests are given and the number of A's on each test is recorded. There will only be on number of A's on each test, so that will be a function.
However, the statement says the teacher records the number of A's on "A" test. Taken literally, that means the SAME test is given (to different classes?) several times. Then the relation will not be a function, because there is only one input (the single test) with several outputs.
NOTE.... If these several posts are from the same assignment from the same teacher, that teacher needs to learn to write problems in which the meaning is completely clear....
