Course Learning Goals
Students will:
- factor polynomials using the distributive property, reverse foil, grouping, the difference of squares, sum and difference of cubes;
- perform operations on rational expressions, radical expressions, and complex numbers; solve rational and radical equations;
- solve compound inequalities, absolute value equations and inequalities;
- solve quadratic equations by using factoring, the quadratic formula, and completing the square and solve relevant applications;
- use function notation, perform operations with functions including composition of functions, find the inverse of a one-to-one function, graph quadratic, exponential, and logarithmic functions, and identify the domain and range of a function; and
- use properties of logarithms to solve logarithmic and exponential equations and relevant applications

Assessment Methods for Course Learning Goals
The student applies mathematical concepts and principles to identify and solve problems presented through informal assessment, such as oral communication among students and between teacher and students. Formal assessment consist of open-ended and multiple choice questions reflecting theoretical and applied situations.
The final exam must be at least 20% of the course grade. Study guides, formula sheets, and other aids may not be used on the final exam.
A minimum of 70% of a student's grade must be determined from proctored assessments and work. These proctored assessments include tests, quizzes, departmental final exam, or other proctored in-class assignments.
