Review Sheet, Exam 2
March 2, 2011
March 9, in class
Sections 1.4-1.8, 2.1, 2.3.
The test will be closed book, closed
notes. You will have the entire class period for the test. Calculators will be
allowed, but will not be required, nor will they be particularly useful.
You may not use a TI-89 or a TI-92.
- You've seen what my exams are like now: a long test with nothing terribly tricky, nothing that
you haven’t seen before. All the advice from the last review sheet still applies. Let's review:
- Practice. A bunch.
Practice a whole lot. The
test will be rather straightforward, and all problems on the test will be
similar to problems from the homework and quizzes (but of course you should
expect the more difficult problems to appear on the test). As always, go
through all of the notes, homework problems, and quizzes. Do extra problems
from the book that are similar to problems you have difficulty with. Any type
of problem assigned in class is fair game for the exam. You should also practice doing these
problems in a test-type situation: no notes, no book, no checking your answer immediately
after doing the problem.
IS AN ISSUE! You have 50 minutes
for this exam. If you understand
the material well enough, then this will be more than enough time for
the test. But if you don’t have a good grip on
the material, then you will go slower, and you may run out of
MyMathLab, all book problems are accessible throuhg the online text
(found in "Chapter Contents") or through the study plan (found in
"Study Plan"). You can practice either of these until your heart
is content, but make sure you can do the problems without any computer
- Finally, you should run through the
review problems and chapter test at the end of chapter R. Since all of the topics appear at the
same time, these exercises will give you a better idea of what the test will be
Equations: Be able to solve a quadratic equation. I may force you to use a
particular method for solving, for instance I may force you to use
completing the square. So
make sure you know all methods.
All quadratics on the exam will have real solutions (no complex
solutions), but you can expect square roots in an answer. Practice Problems: 1.4, 13-22, 31-40, 45-48, 53-59.
will only be geometric word problems, probably dealing with a rectangle
or a box (think garden borders, cardboard being folded, etc).
Make sure you answer the question you are being asked (if I ask for a
box's dimensions, make sure you give them to me). Practice Problems: 1.5, 15-24..
Types of Equations: Radicals, rationals, and substitution. Be able to do all three. Be able to do radical equations
with two square roots, and MAKE SURE YOU CHECK YOUR ANSWERS!!! Practice Problems: 1.6, 7-26, 35-70, 73-85.
Linear and quadratic inequalities.
Be able to solve them, and be able to draw the solution on a number
line and be able to write the solution in interval notation. Practice Problems: 1.7, 13-34, 39-48, 69-86.
Equations and Inequalities: Solve equations and inequalities involving
absolute values. Make sure
you isolate the absolute value before getting rid of it, and make sure you
end up with two answers to the absolute equations. Practice Problems: 1.8, 9-23, 27-41, 43-66.
Coordinates: Plotting points, finding distances and
midpoints. Most of this section
is just formulas. Just make
sure you know how to plug stuff into the formulas, and make sure you get
the formulas right. Practice
Problems: 2.1, 11-18, 31-36.
and Graphs: Not much here.
You need to be able to find the domain and range of a function,
either from the function’s formula or from the graph. Also, you should be able to interpret
a graph of a function, determining values of f(x) from the graph. Practice Problems: 2.3, 23-38, 41-56.
