Learning Objectives

  • Recognition of function model groups by name, equation, and general graph shape: linear, quadratic, cubic, general polynomial, rational, trigonometric, inverse trigonometric, exponential, and logarithmic.
  • Recognition of conic sections by their equations, both Cartesian and polar. Use of completion of the square for Cartesian and equivalent fractions for polar coordinates to put the equation in standard form. Use of the standard form to sketch the graph of the conic.
  • Vocabulary used to describe graphs including, but not limited to: domain, range, increasing, decreasing, x-intercept, function zero, y-intercept, maximum, minimum, asymptote, vertical, horizontal, axis, scale, coordinates, vertex, axis of symmetry, center, foci, period, amplitude, phase shift, vertical shift, and end behavior. 
  • Real number line and solving inequalities to describe number sets on that line.
  • Complex number arithmetic and application of the fundamental theorem of algebra to factor polynomials.
  • Algebraic techniques for problem solving together with reasoning and argumentation skills needed to present mathematical arguments and proofs.

Method of Evaluation Grading Scale

90—100% A
80—89% B
70—79% C
60—69% D

Final grade = 85% of test average (four tests) and 15% quiz average. There will be a short quiz given every class period to check on homework.

Calculator Policy:

Students must have a TI-89, or TI-83, or TI-84 graphing calculator and bring it to every class session. If you plan to go on to a higher math course, a TI is the best choice. The TI-83 Plus may be purchased on EBay for around $40.

Make-Up Policy:

Makeup tests will be left up to the instructor. Usually, if a test is missed, the Final Exam grade will be substituted for the missed test. You will receive a grade of zero on your second missed test.

Attendance Policy:

Attendance ensures that you get notes which will help you learn the material being covered and allows you to learn from questions being asked and answered in class. Five or more absences could result in a lower or even failing grade.
