Module 3 Summary

When snowboarders jump, the path they follow is in the shape of a parabola. When projected into the air, most objects have a trajectory shaped like a parabola. You learned to model these trajectories, as well as structures and commercial situations, using quadratic functions.

 

In Module 3 you learned what a quadratic function is. You discovered that there are three different forms of the quadratic function. You developed the ability to convert between these forms and answer questions about trajectories, maximizing profits, and other situations. You developed skill at sketching and graphing models of situations that relate to quadratic functions.

 

You discovered more of the capabilities of your graphing calculator. You used these capabilities to answer questions and verify results. You began to model situations using quadratic functions in order to answer questions about the situations.

 

The Module 3 Project involved using quadratic functions to compare trajectories to evaluate three different teams competing in an egg-throwing contest. You compared the heights and distances of tossed eggs using tables, graphs, and equations. You converted back and forth between these methods of expression to determine the contest winner.

 

In Module 4: Statistical Reasoning, you will investigate how data can be analyzed and used to solve problems and will learn how to determine the reliability of statistical claims.
