Since it looks like you guys need some reminders on how to evaluate arithmetic and geometric series (from Ch. 1), here are two videos that I made that go over just that: Evaluating an arithmetic series (5 minutes and 47 … Continue reading
Completing the Square for Vertex Equation
Since completing the square has a lot of steps and it’s easy to forget some of them after a while, I went back and made a video for this topic. See http://blip.tv/file/4866146 (5 minutes and 7 seconds) It shows how … Continue reading
Function Transformations
Here’s a video for an earlier topic: function transformations. (I am going to go backwards and make the videos for the trickier old topics.) I apologize in advance for the choppiness of my explanation. You can still follow it, and … Continue reading

Here is a video that goes over how to find the domains of composition functions. I showed in the previous video how to get these composition formulas, so this video only discusses the domains of those results. http://www.blip.tv/file/4857894/ (7 minutes and … Continue reading
Composition Functions – How to Write Their Equations
Here is a video about how to write the function equations for composition functions (f o g)(x), (g o f)(x), and (g o g)(x). http://www.blip.tv/file/4856488 (6 minutes and 50 seconds long) Note: This will be followed by another video (soon!) that shows you how … Continue reading
Domains of Combination Functions
I made a twopart video showing you how to find/predict the domains of combination functions f+g, fg, fg, f/g, and g/f. The Part 1 video goes over how to analyze just the domains of f and g. The Part 2 … Continue reading
