Welcome back! We finished up investigation 3 today. In investigation 3.4 we focused on determining whether or not a function is quadratic by looking at the table. We discovered when you take the second differences of the y-values (subtract the consecutive y-values, then subtract again) the same number results. This can help us determine that the function is quadratic and conversely, if we know the function is quadratic, we can fill in the data table.
Classwork: Today we reviewed answers to the midterm exam. We then started reading about electricity and taking notes. Extra copies of note packets are in the science folder on the blog and we read pages 298-301. Please try to keep up if you are absent!
