Hello, I have a quick question regarding Calculus and what should be covered in pre-cal. I'm currently in a pre-cal course and according to the syllabus it seems the teacher is skipping over quadratic functions. I only noticed because for the most part her course just follows along with the book but the quadratics were one of the few sections not covered. Should I self study? Is there something special about quadratic functions that I need to know for Calc?
