The Class Key for this course is ccri 5324 6224
Class Materials: computer, calculator, internet access, MS Teams
Course Description (4 credits) Functions and their graphs are discussed with particular attention paid to
polynomial, rational, trigonometric, exponential and logarithmic functions. Determinants, matrices, complex
numbers and analytic geometry are also studied.
Note: Per NEASC standards, for each class hour a student is in class, he or she should expect to work 2 hours
outside of class on the material. This means that you should prepare to spend at least 8 hours each week outside of
class on this course. Schedule your time accordingly.
