The concept of functions and their properties form a central theme. Multiple representations of function properties are made possible through the use of the TI-84+ graphing calculator. Polynomial, quadratic, exponential, and logarithmic functions are considered. The course also includes an introduction to matrices as a method of solving systems of equations and the study of descriptive statistics in order to interpret data and make informed decisions. Students may not receive credit for both MTH 140 and MTH 141.
