## Reflection: Diverse Entry Points Explore changing coefficients - Section 2: Play of the Day

This year, I decided to try using a Geogebra platform instead of graphing calculators to illustrate the effect of changing coefficients.  I found it immensely more useful, because the image is just so much bigger and easier to see, and the sliders are so much more intuitive.

See the resource section for the updated classwork file that works with this Geogebra tool.
