Course Student Learning Outcomes (CSLOs):
Upon successful completion of this course as documented through writing, objective testing, case studies, laboratory practice, and/or classroom discussion, the student will be able to:
1. Correctly translate and solve first-degree equations and inequalities.
2. Given a relation, identify if it is a function. If so, find its domain and range, and then correctly evaluate the function given a value in its domain.*
3. Given a linear equation, correctly graph it on a rectangular coordinate system.
4. Find the equation of a line given one of the following:
A point on the line and the slope of the line
Two points on the line
A point on the line and the equation of a line parallel or perpendicular to it
5. Given a system of linear equations, correctly solve the system by graphing, substitution or the addition method.
6. Given a system of inequalities, solve the system by the graphing method.
7. Given two or more polynomials, correctly add, subtract, multiply or divide the expressions.
8. Given two or more rational expressions, correctly add, subtract, multiply or divide the expressions.
9. Given an equation involving rational expressions, correctly solve the equation.
10. Given two or more radical expressions, add, subtract, multiply and divide the expressions and write the answer in simplest form.
11. Given two complex numbers, add, subtract, multiply or divide the numbers and write the answer in the form a + bi.
12. Given a quadratic equation, solve it by factoring, taking square roots, completing the square or using the quadratic formula.
* This course objective has been identified as a student learning outcome that must be formally assessed as part of the Comprehensive Assessment Plan of the college. All faculty teaching this course must collect the required data and submit the required analysis and documentation at the conclusion of the semester to the Office of Institutional Research and Assessment.
