Official Course Competencies

By the time the student completes this course of study, the student will know or be able to:

1. Analyze and interpret the behavior of functions, including end behavior, increasing and decreasing,
extrema, asymptotic behavior, and symmetry.
2. Solve polynomial, rational, exponential, and logarithmic equations analytically and graphically.
3. Find real and complex zeros of polynomial functions analytically and graphically.
4. Graph polynomial, rational, exponential, logarithmic, power, absolute value, and piecewise-defined
functions.
5. Determine domain and range of polynomial, rational, exponential, logarithmic, power, absolute value,
and piecewise-defined functions.
6. Use transformations to graph functions.
7. Perform operations, including compositions, on functions and state the domain of the resulting

9. Determine whether a function is one-to-one when represented numerically, analytically, or
graphically.
