Modeling Quadratic Functions: Graphs and Equations

The video tutorial explains how to model quadratic functions by drawing graphs and writing equations. It begins with a comparison of linear and quadratic functions, emphasizing the use of slope-intercept form for linear functions. The concept of squaring numbers is introduced, leading to the explanation of quadratic patterns. The tutorial demonstrates how to graph quadratic functions and highlights their differences from linear functions, such as their curved shape and symmetry. Finally, it provides a problem-solving example using quadratic equations and graphing techniques.

What does it mean when we say that the square of a negative number is the same as the square of its related positive number?
