TI Explorations books has a great activity for TI InterActive!™ in graphing parabolas in vertex form. What if you don't have TI InterActive! or a lab to take your students, but you do have a class set of TI-83 or TI-84. This activity explores the affects of a, h, and k on the function y=a(x - h)^2 + k on the reference graph y = x^2.
Before the Activity
Students should have access to either the TI-83 or TI-84 family of calculators.
During the Activity
Step by Step directions on graphing parabloas in vertex form is included in this document. Screen captures are included to guide the student.
After the Activity
Follow up assignment after exploration is completed. The Word document is student handout. The TI InterActive! file is the solutions.
