MAC 1140. Precalculus Algebra (3). Prerequisite: MAC 1105 or appropriate score on a mathematics placement examination. May be taken concurrently with MAC 1114. Credit must be reduced to two (2) hours for students having a grade of "C-" or better in MAC 1141. (In cases in which a student has earned a "D+", "D", or "D-" in a course and subsequently takes a similar course at the same level, the hours toward graduation for the first course will be disallowed as soon as the student passes the second course. These cases are: MAC 2233 after MAC 2311; MAC 2311 after MAC 2233.) Functions and graphs, with emphasis on higher degree polynomial, rational, exponential, and logarithmic functions; systems of equations; solution of linear systems, matrix methods, determinants; sequences and series, induction, and the binomial theorem.
