## TAKS Activities - Objective 5: Quadratic Functions

#### Activity Overview

Ad1(D) For problem situations, the student analyzes graphs of quadratic functions and draws conclusions

#### Before the Activity

If you are using the TI-Navigator System with the TI-73 you will need the attached .pdf file.
The quadratic function h(t)=-16t?+vt+h can be used to model the path of a ball thrown vertically with an initial velocity of v ft/sec from an initial height h. Use your handheld grapher to analyze the path of the ball and to answer the accompanying questions.

#### During the Activity

After collecting the data from students, a spreadsheet may be used to perform all the calculations at once (see attached samples).
