MAT 045 - Introduction to Precalculus3 equivalent hours - Three hours weekly; one term.
Study intermediate algebra topics focused on the essential skills and applications required for MAT 145 - Precalculus 1. Topics include algebra of linear, rational, and radical expressions; algebra, composition, and inversion of functions; quadratic, rational, radical, absolute value, and systems of linear equations; linear, compound, and absolute value inequalities; and graphing linear, nonlinear, quadratic, exponential and logarithmic functions, including translations and reflections, and systems of inequalities.
Prerequisite(s): Appropriate score on AACC’s mathematics placement measures, or completion of MAT 044 with a grade of C or higher, or successful completion of an approved mathematics preparation course.
Note: MAT 045 and MAT 145 may be taken in the same semester. A grade of at least C is required in MAT 045 to start MAT 145 .
