Homework
In case you miss a homework assignment in class, you can find it below.
Unless otherwise specified,
all problems
are from the 3rd Edition
of Elementary & Intermediate Algebra published by Pearson.
See the grading policies
for general instructions on doing homework and how it will be graded.
You can always do more homework problems!
You may need to practise the material
if you want to remember it
for the final exam,
a subsequent course, or the rest of your life.
If you bought MyMathLabPlus access
with your course textbook (or separately),
then you can find supplementary problems there;
see the MyMathLabPlus instructions.
(However, MyMathLab is not required for this section.)
