Hi there, I'm currently in a Grade 12 (in Canada) mathematics course… And I'm having trouble graphing polynomials.

I have no idea where to start, or what to do!

I currently use a graphing calculator to make graphs, but I believe that I won't be able to use one on my exam.

So, I really need to learn before my exam… And I can't seem to understand the tutorials I read online, they don't show me how to graph functions like "f(x) = -3x^2 + 5x +2".

Can anyone recommend a good tutorial, or perhaps explain how I'm supposed to graph these things?

Thanks!
