Question

Are there any notes on sketching graphs I can't solve nearly any question in the problem set.

Answer 1

There are notes here

Also, you can use Khan's site:
Here is a video on graphing a parabola whose equation is in vertex form

You will also want to know how to convert "standard form" in the problem set to vertex form, by "completing the square"

Answer 2

Thanks
