The first exam

The first exam will be on Wednesday, February 8.  It will consist of seven problems.  Be sure you are prepared, because you may be slightly pressed for time.  A reasonable preparation is to do carefully all of the problems in the syllabus and to review the methods and techniques you used to solve these problems.  You may want to pay particular attention to
• interpretation of graphs in word problems;
• determining whether or not tabular data can represent a linear relationship, and writing down the corresponding equation if it does;
• determining whether or not tabular data can represent an exponential relationship, and writing down the corresponding equation if it does;
• determining whether descriptions of real-world situations correspond to increasing or decreasing functions, and whether such descriptions correspond to concave up or concave down functions;
• working with supply and demand curves, and determining the effect of taxes levied on either producers or consumers on the equilibrium price and quantity;
• working with exponential growth and decay (half-life, etc.);
• compositions, translations, and scalings of functions, and corresponding interpretations of these operations in applications.

The second exam
The second exam will be on Wednesday, February 22.  Be sure to bring your student ID to this particular exam.
The exam will cover the material in Chapter 2 of the text.

• Be able to interpret points on a graph corresponding to where a function is increasing, decreasing, concave up, and concave down, in terms of whether the  function, its first derivative, and its second derivative are positive, negative, or zero.
• Be able to draw a plausible graph of a function, given a description of a hypothetical real-world situation.
• Be able to compute approximate values of the derivative of a function, when values of the function are given in a table.
• Be able to interpret the shape of the graph of a function in terms of the second derivative of that function.
