Finding Zeros of Quadratic Functions with Tables of Values

This lesson teaches how to find zeros of quadratic functions by examining tables of values. It uses examples involving a toy rocket, a soccer ball, a rocket launched from a building, and a baseball to illustrate the concept. The lesson emphasizes the importance of considering the domain of the function and understanding the context of the problem to accurately determine when an object hits the ground. By the end, students should be able to identify zeros of functions using tables and understand the significance of domain in these calculations.

Why is it important to consider the domain of a function when determining when an object hits the ground?

In the baseball example, why is the time of 0 seconds not a solution for when it hits the ground?

What conclusions can be drawn about the number of solutions for different objects hitting the ground?
