Course Description

Reasoning with Functions II is designed for students who have completed Reasoning with Functions I, and plan on taking calculus courses or coursework requiring a thorough understanding of functions and algebraic reasoning. It provides the opportunity to use multiple representations and explicit covariational reasoning to investigate and explore quantities, their relationships, and how these relationships change. Students use their knowledge of functions to model and solve problems involving algebraic and transcendental functions and equations. Students also develop algebraic tools necessary to model and solve problems using trigonometric functions and their properties

Evaluation Criteria/Policies

The grade will be determined using the Delaware Tech grading system:

90-100	=	A
80-89	=	B
70-79	=	C
0-69	=	F

Students should refer to the Catalog/Student Handbook for information on the Academic Standing Policy, the Academic Integrity Policy, Student Rights and Responsibilities, and other policies relevant to their academic progress.
