Chapter 1: Polynomial Functions
Throughout this chapter, you will explore how the curves represented by polynomial functions are applied in various
design-related fields such as civil engineering, architectural design, computer graphics design, interior design, and
landscape architecture.
By the end of this chapter, you will be assessed on your ability to:
C1.0
D1.0
identify and describe some key features of polynomial functions, and make connections between the numeric,
graphical, and algebraic representations of polynomial functions.
demonstrate an understanding of average and instantaneous rate of change, and determine, numerically and
graphically, and interpret the average rate of change of a function over a given interval and the instantaneous rate
of change of a function at a given point.

The Chapter will wrap up with a review, the Chapter 1 Task and a written test. Class discussions, class work, homework
and quizzes will help you to determine how well you understand the course material in preparation for the summative
assessments.
Extra help is available with me upon request.
There is free tutoring and instructional videos available on the class moodle.
