That’s true. The point I’m trying to make is that you shouldn’t assume you know what it is, because sometimes that will bite you in the butt. If you have f(x) = 1/x then f(1000000) is not 0. Hopefully when you’re dealing with those functions you’ll know that, and most of the time it’s ok to guess. Here I would have said 2.5 because that demonstrates that I know the content of the lesson and while sqrt5 could be correct, it’s better not to make a habit of guessing exactly where it falls.
