Light It Up
- John Golden
I made this interactive for the NCTM Illuminations activity 'Light It Up' from http://illuminations.nctm.org/Lesson.aspx?id=1968 Set the mirror position and laser height. Then collect data for how high the spot on the wall is (output) for how far from the wall you're standing (input). Can you find a function rule for this input/output? Type your rule into the input bar to see if it matches!
Hint: the lesson suggests y =a+b/(x-c) for a rule form. More GeoGebra at bit.ly/mh-ggb
