Graphing Quadratic Equations to Solve Real World Problems

This lesson teaches how to solve real-world problems using graphs of quadratic equations. It covers key features of parabolas, such as zeros, vertex, and axis of symmetry. The lesson explains the importance of considering only positive zeros in time-related problems. Two example problems are analyzed: one involving a water balloon and another involving a ball, demonstrating how to determine the time in the air and maximum height using graphs. The lesson concludes with a summary of the problem-solving process using quadratic graphs.

Discuss the importance of considering only positive values for time in projectile motion problems.

What does the maximum height of a projectile represent in the context of its graph?
