Rational and polynomial functions
In this unit, provided by New Visions for Public Schools, students will study properties of rational and polynomial expressions as they appear in both functions and equations. They will also use solving polynomial equations of various forms to extend the number system into the Complex Plane.
Essential Questions:
- How do changes in the symbolic representation affect the graphical representation of the function?
- What are the key features of a polynomial function and what do they mean in the context of a problem?
- How do the properties of real numbers apply to imaginary numbers? How can polynomial, radical, or rational functions model problems?
- Why are solutions considered "extraneous"?
- How do rational and polynomial functions occur?
