Today was a busy day in Math II. We talked about graphing quadratics. We discussed the different important points, lines, and other information that must be known about a parabola. We discussed the difference between an x-int and a zero. We talked about increasing interval, decreasing interval and its difference from the end behavior. We went through graphing by hand and how to do it using a calculator as well. It was a very busy day and we will continue with it more tomorrow. Here are the notes from period 1, period 3, period 4.
