You've Come A Long Way Baby
We graphed a third degree polynomial equation today. We used minimum and maximum points. We used concavity and inflection points. When we finished, we compared our results to the results on the graphing calculator. The kids were amazed at how accurate our picture was. The teacher who entered the room as my class was ending was impressed.
I told the class to remember when graphing straight lines was a challenge. One boy took the picture above. They've come a long way, baby!
