The first exam will cover chapters 1-3.  You should review your homework, class notes, and the textbook.  Below is a list of topics with related problems and a list of some word problems from the review sections.  Do as many of these as you need to understand these concepts.  The problems on the exam are likely to be more challenging than the quiz problems.

List of topics and some representative problems

• Equations of lines, slopes, and meaning of slope (likely be part of another problem or in a word problem)
  
• Exponential growth and decay, both continuous and discrete (1.2 #57-66; 2.1 #13-30)
  
• Creating and understanding semilog and log-log plots (1.3 #43-89)
  
• Recursion relations: using them, fixed points, word problems (2.2 #83-110, also problems from 2.1 given above)
  
• Population models (see additional word problems below)
  
• Computing limits (3.1 #37-54; 3.2 #29-48; 3.3 #1-24; 3.4 #1,2,5-15)
  
• Knowing when and why limits do not exist (3.1 examples 3-6)
  
• Understanding and applying the definition of continuity (3.2, #5-12, 27, 28)
  
• Intermediate value theorem; using and understanding the accuracy of the bisection method (3.5, #4-8)

Some additional word problems from the review sections.  All of the topics are not represented in these problems, but these are good examples of word problems that are appropriate for the exam.
