Functions are just basic y=x equations, except the "y" is represented by the term f(x). But because it's not y, and it's f(x), you can't square f(x), so a circle([y^2]+[x^2]=1) is not a function. A far easier way to do this is something called the vertical line test. Plot the function by hand of on your calculator, and make an imaginary vertical line, if that line touches more that one place on the graph, then it is not a function. Parabolas are a basic function that will be on the SAT, f(x)=x^2, they pass the vertical line test. I hope that made some sense.....lines are functions too. Good luck on your SAT.
Nono, I get that... The library book I am studying from has much more complex ones than that, where I don't exactly know what the hell is going on. I understand the part you just wrote about, though; Sorry I wasn't specific.
We will be fail buddies! Usually, Hannah is my fail buddy, but on this special occassion I think everyone deserves an equal shot at being a fail buddy...
Well, good luck. I'm very very sure you will do much better than me, so don't worry about it.

Hey, let's try to find each other in the morning, because I do not want to be squished in with oh-my-god-who-the-hell-are-you people.
Good luck to you too.
