MATH 138College Algebra for Business & Social Science• 5 Cr.

Description:

Examines graphs, non-trigonometric elementary functions, systems of equations and inequalities, and probability, emphasizing uses in business and social science. Either MATH& 141 or MATH 138 may be taken for credit, not both. MATH 138 is required before taking MATH& 148. Fulfills quantitative or symbolic reasoning course requirement at BC. Prerequisite: Placement by assessment, or MATH 099 with a B- or better.

Outcomes:

After completing this class, students should be able to:

• Understand the concept of a function; recognize linear functions; compute the slope and the equation of a line; set up and solve application problems using linear functions.
• Recognize and apply quadratic functions, polynomial functions, and rational functions.
• Recognize and apply exponential functions; solve applications using exponential functions and logarithmic functions; solve applications using logarithmic functions.
• Understand and apply the echelon method and Gauss-Jordan method ; perform matrix operations including matrix multiplication; find an inverse matrix; apply matrix methods to solve applications problems.
• Graph linear inequalities in two variables; solve linear programming problems graphically; solve applications of linear programming; understand and compute solutions using the simplex method (optional).
• Understand and use sets, Venn diagrams, tree diagrams and tables to calculate probabilities and interpret them in applied context and conditional probability.
• Optional topics: compute simple interest and discount, compound interest, annuities, present value of an annuity, and amortization.
