- perform operations of functions: addition, subtraction, multiplication, division, and composition.
- find the inverse function and its graph.
- construct mathematical models with functions, using real-world applications or formulas.
- determine zeros of a function, symmetries of a function; use limits to determine end behavior of a function.
- solve problems involving maximizing and minimizing a quadratic function, both algebraically and graphically.
- find vertical, horizontal, and slant asymptotes for rational functions and graph.
- graph exponential and logarithmic functions, and accurately use the properties of logarithms and the definition of e.

Assessment Methods for Core Learning Goals:All Core Critical Thinking and Problem Solving, College Level Mathematics or Science, and Discipline-Specific Course Objectives will be assessed as follows:
The student will apply mathematical concepts and principles to identify and solve problems presented through informal assessment, such as oral communication among students and between teacher and students and, for the core, formal assessment using open-ended questions reflecting theoretical and applied situations.
Reference, Resource, or Learning Materials to be used by Students:Departmentally selected textbook and graphing calculator is required. Details provided by the instructor or each course section. See Course Format.
Teaching Methods EmployedPrimary teaching methods are lecture, recitation, problem solving, and class discussion as appropriate.
