SoapFYI, This is a function.
This is a function because
1) Every x has a corresponding Y
2) Because it passes the vertical line test
Also, this is a polynominal equation. As for finding the equation of the line, you need to find its zeros and work from there. I only know the calculus way, I am not sure how they do it in your class.
I strongly recommend looking at khan-academy for any math questions. It is very comprehensive.
