''State the domain and range of each relation. Then state whether the relation is a function. Write yes or no.''

22. {(5, 5), (6, 6)}

For the Domain, I got {(5)} and for the range, {(6)}.

The correct answer is {(5, 6)} for the domain and {(5, 6)} for the range.

I was correct that it was a function.

''The symbol [x] means the greatest integer not greater than x. If f(x) = [x] + 4, find each value.''

37. f(π)

I got 3.14 + 4 = 7.14.

However, the correct answer is supposed to be 7?

Why?

39. f(q+1)

I got q + 5.

The answer is supposed to be [q] + 5.

Is that correct or would it be marked wrong on a test if I didn't include the brackets?

Thanks in advance.
