• Describing the end behavior of a polynomial function given its degree and leading coefficient

Another Way of Factoring
Students will find factors for quadratic equations with a leading coefficient of one. The students will then graph these equations using a graphing calculator and analyze the factors and the graphs of the equations in order to determine a relationship between the two. This relationship will then be used to help factor more difficult polynomial equations. Students will also explore a real-life application in physics.

Building Boxes (Polynomial and Rational Functions)
In this lesson, students investigate rational and polynomial functions. Students determine the maximum volume of a box. It has a video of the lesson available online for the teacher.
