Today’s soundtrack is Space Junk is Forever: Space Junk is Forever, a really cool progressive synth rock album. It sounds like what could happen if Tangerine Dream and Dream Theater collaborated. Amazing stuff!
This afternoon, I’m on to the final assignment before I can write this unit test. In this unit, I’ve been working on quadratic functions. I’ve learned the following:

Properties of a Quadratic Function

Quadratic Functions in Standard Form

Completing the Square

Analyzing the General Form

Word Problems
I needed to review a few concepts:

If I start with the graph of y = x² and want to make congruent parabolas in different places, I can do the following:

y = (x2)² will be two units to the right

y = (x+2)² will be two units to the left

y = x²2 will be two units up

y = x²+2 will be two units down
The interactive quadratic function app on intmath.com helped me a lot with understanding this concept, and it runs a heck of a lot faster than my calculator does!
