Course Description
Explores relations and functions graphically, numerically, symbolically, and verbally. Examines exponential, logarithmic, polynomial, and rational functions. Investigates applications from a variety of perspectives. Graphing calculator required. TI89 Titanium or Casio ClassPad recommended. The PCC math department recommends that students take MTH courses in consecutive terms. Prerequisites: MTH 95, RD 115, and WR 115, or equivalent placement. Recommended: MTH 95 taken within the past 4 terms. Audit available.Intended Outcomes for the course
Upon successful completion students should be able to:
 Demonstrate an understanding of functions including function notation, function algebra, domain/range, inverse functions, piecewise functions, graph transformations, and symmetry.
 Analyze polynomial, rational, exponential, and logarithmic functions represented numerically, symbolically, verbally and graphically and identify properties of these functions using technology.
 Use variables to represent unknown quantities; create models; solve exponential, logarithmic, polynomial, and rational equations; and interpret the results.
 Demonstrate a mastery of the skills necessary for future course work that requires the use of college algebra concepts.
Course Activities and Design
All activities will follow the premise that formal definitions and procedures evolve from the investigation of practical problems. Inclass time is primarily activity/discussion emphasizing problem solving techniques. Activities will include group work.
Outcome Assessment Strategies
Assessment shall include:
 The following must be assessed without the use of books, notes, or calculators, in a proctored setting:

Algebraically

Evaluating logarithmic expressions

Solving logarithmic equations

Solving exponential equations

Function algebra


Graphically

Graphing Polynomials

Graphing Rational functions

Transformations of functions



At least two proctored, closedbook, no notes exams, one of which is a comprehensive final exam that is worth at least 25% of the overall grade. The proctored exams should be worth at least 60% of the overall grade. These exams must consist primarily of free response questions although a limited number of multiple choice and/or fill in the blank questions may be used where appropriate.

Various opportunities to express and be graded on mathematical concepts in writing. Assessment should be made on the basis of using correct mathematical syntax, appropriate use of the English language, and explanation of the mathematical concept.

At least two of the following additional measures:

Takehome examinations

Graded homework

Quizzes

Group projects

Inclass activities

Portfolios

Individual projects


Additional forms of assessment that do not have to be part of the grade:

Attendance

Individual student conference

Inclass participation

ADDENDUM
Documentation Standards for Mathematics
All work in this course will be evaluated for your ability to meet the following writing objectives as well as for "mathematical content."
 Every solution must be written in such a way that the question that was asked is clear simply by reading the submitted solution.
 Any table or graph that appears in the original problem must also appear somewhere in your solution.
 All graphs that appear in your solution must contain axis names and scales. All graphs must be accompanied by a figure number and caption. When the graph is referenced in your written work, the reference must be by figure number. Additionally, graphs for applied problems must have units on each axis and the explicit meaning of each axis must be selfapparent either by the axis names or by the figure caption.
 All tables that appear in your solution must have well defined column headings as well as an assigned table number accompanied by a brief caption (description). When the table is referenced in your written work, the reference must be by table number.
 A brief introduction to the problem is almost always appropriate.
 In applied problems, all variables and constants must be defined.
 If you used the graph or table feature of your calculator in the problem solving process, you must include the graph or table in your written solution.
 If you used some other nontrivial feature of your calculator (e.g. SOLVER), you must state this in your solution.
 All (relevant) information given in the problem must be stated somewhere in your solution.
 A sentence that orients the reader to the purpose of the mathematics should usually precede symbol pushing.
 Your conclusion shall not be encased in a box, but rather stated at the end of your solution in complete sentence form.
 Line up your equal signs vertically.
 If work is wordprocessed all mathematical symbols must be generated with a math equation editor.
