Course Learning Outcomes (CLOs):
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.Given a set of real numbers, display the set in set-builder notation, interval notation or by graphing the set on a real number line.
2.Given an absolute value linear equation or absolute value linear inequality, solve the equation or inequality.
3.Given a system of linear equations, correctly solve the system by the addition method or by using determinants.
4.Given two or more radical expressions, add, subtract, multiply or divide the expressions and write the answer in simplest form.
5.Given two complex numbers, add, subtract, multiply or divide the numbers and write the answer in the form a + bi.
6.Given an equation that reduces to a quadratic equation, correctly solve the equation by factoring, taking square roots, completing the square or using the quadratic formula.
7.Given a quadratic inequality or rational inequality, correctly solve the inequality.
8.Given a quadratic, cubic, absolute value or square root function, correctly graph the function.
9.Given two functions, add, subtract, multiply, divide or find the composition of the functions.
10.Given a 1 - 1 function, find its inverse.
11.Given an exponential expression, write it in logarithmic form, or vice versa.
12.Given an exponential or logarithmic function, correctly graph the function.
13.Given an exponential or logarithmic equation, correctly solve the equation.
14.Given the equation of one of the four basic conic sections (parabola, circle, ellipse or hyperbola), identify the type and graph the equation.
15.Given a system of nonlinear equations or inequalities, solve the system by substitution or graphing.*
16.Given an angle in degree or radian measure, convert between the two forms.
17.Given two sides of a right triangle or a point in the coordinate system, evaluate any of the six trigonometric functions for the corresponding angle.
18.Given the equation y = sinx or y = cosx, graph the equation.

* 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.
