Okay I want to be clear, this is not an homework question.

But I have a hard time understanding the concept of what I'm going to show you. The teacher goes way to fast for me, honestly, and when we ask a question it's just like he doesn't want to take the time to make us understand, kinda makes me feel stupid.

So I'm writing me question with the hopes that you can point me a tutorial (hopefully video) or if you are good in the subject and can help me a little. I just want to grip the concept so I can have fun doing those because I'd understand...

I believe there an equation that's like y = a (x - h)² + b

You know, I think I understand 80% of that factorization thing, but I have no clue about the parabola.

Things I'd like to know and remember:

- How to know if the parabola is pointing and how much is it "open" (I hope you understand what I mean).

- How to place the parabola at the good place (the - h thing lost me).

- The canonical form, what's the big deal ? Why can't it be simpler :|

I'm sorry if this is a stupid question but when I look at my notes it's all just whatever (the teacher goes so fast, I spend the time writing wh he writes on the chalkboard but I can't follow)

thank you
