- Exercise due on April 19 Monday (submit these on Canvas):
Suppose that you have
a rational inequality in one variable that you wish to solve.
You investigate the inequality and discover the following facts about it:
- the left-hand side is always defined;
- the right-hand side
is undefined when
*x*is 2 but is otherwise defined; - the left-hand side and right-hand side
are equal when
*x*is −3/2 and only then; - the original inequality
is true when
*x*is −3/2 or 3 but false when*x*is −2, 0, or 2.

- Reading:

- Graphs and functions:
- Review date: September 10 Friday (in class).
- Date taken: September 13 Monday (in class).
- Corresponding problem sets: 1–12.
- Help allowed: Your notes, calculator.
- NOT allowed: Textbook, my notes, other people, websites, etc.

For the exam, you may use *one sheet of notes* that you wrote yourself;
please take a scan or a picture of this (both sides) and submit it on Canvas.
However, you may not use your book or anything else not written by you.
You certainly should not talk to other people!
Calculators are allowed, although you shouldn't really need one,
but not communication devices (like cell phones).

The exam consists of questions similar in style and content to those in the practice final exam on MyLab.
