About This Lesson
The traditonal textbook generally presents the quadratic model in standard form for students to work on. Students only need to be familar with certain formulas for answers. However, students may not have ideas where the model come from and how the real life scenarios can contribute to quadratic model. Therefore, I google out the example on the web* and rewrote this example for my students. They are expected to build up knowledge about how quadratic model is created through this activity. *Source: http://www.purplemath.com/modules/quadprob3.htm
