The Latest in Analytic Geometry

Test # 2 is graded and will soon be posted in Power School.  Thanks for your patience.  There are so many ways to gain some partial credit that it takes a while to get an accurate grade on these kinds of assessments.

We started our study of Unit 3 on Friday, 9/11/2015.  Now that we have spent so much time working with quadratic functions algebraically and solving quadratic equations by completing the square, factoring, and using the Quadratic Formula, we are turning our attention to graphing quadratic functions.

We have learned that the graph of a quadratic function is called a parabola, and the important features of parabolas are the vertex and the axis of symmetry.

Below are copies of some of the handouts we have looked at in class as well as links to videos, lessons, practice, and other cool web resources for parabolas.

PS:
Please get one of these...  I don't care where you buy it from.  I don't care if you use big sister's old one.  I don't care what kind of TI you get (or other brand, but I really really really like Texas Instruments calculators).  I can't make you buy one.  But, if you don't have access to a calculator and you have been trying to borrow one of the rescued calculators I have to solve the arithmetic problems you have not been able to solve on your own, then please please please get ahold of one to use.  You will be glad!
