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.
