Graphing problem.....?

The function f(x) = -3x + 9 is de fined on the interval [0; 3].

But if you plug in 0, you don't get 3. How do I graph this?

Normally it would give 9.

The question in its entirety is on page 909 in this link:http://books.google.com.bz/books?id=El9Cx2mIEQIC&p...

Update:

f(0) isn't equal to 3 though. f(0) = 9. That's the problem.

    The geometric figure of that function is a line. I don't see what's so difficult about it.
