Alg 2 - Finding Zeros and Points of Intersection on a Graphing Calculator

This activity is broken into seven parts.

Part I: Guides students in noticing that the trace key may not locate the x-intercepts (zeros) but shows them that there is another way x-intercepts can be found.

Part II: Illustrates that there are algebraic techniques that can be
incorporated in finding zeros.

Part III: Shows student show to use a built-in feature to find x-intercepts or zeros.

Part IV: Investigates how tables can be used to find x-intercepts and/or points of intersection.

Part V: Challenges students to use the illustrated methods to find where 2^x=x^2 .

Part VI: Students are challenged with 5 additional exercises.
