This course introduces the mathematical concept of the function by extending students’  experiences  with  linear  and  quadratic relations. Students will investigate properties of discrete and continuous functions, including trigonometric and exponential functions; represent functions  numerically,  algebraically, and  graphically; solve problems  involving  applications of functions; and develop facility in  simplifying  polynomial  and  rational  expressions.  Students  will reason mathematically and communicate their thinking as they solve multi-step problems.
