# Function Matching – Down the Desmos Rabbit Hole!

Before our break I created a set of challenges for students to investigate translations of different functions. I had a few goals in mind:

• Introduce a few basic functions that we will work with in this unit (square root, rational, cubic, quadratic).
• See how certain points on the function are translated.
• How does affecting the values in the equation affect the graph of a variety of functions?
• Use function notation to represent translations.

# The Power of Match My Graph

I was checking out twitter last week and ran into this from Dan Meyer:

and I had a concept coming up that I have always had a tough reaction to. I threw it out there.

To get students to be interested in it I wanted them to be “dying” to figure it out.

I thought about putting them in a place where they had to struggle— I wanted to open up the middle!
Michael Fenton has a series of Match my Parabola challenges and I thought of those. I modified his challenges a bit to include those examples from my tweet.
