Section 3.5 introduces relations, functions, and
functional notation. The next section relates functions and
relations to graphs. Chapter 4 is about systems of
equations. Section 4.1 covers systems of two equations with two
variables. Sections 4.2 and 4.3 talk about word problems that can
be done more easily if you use more than one variable in setting up the
equations. In 4.3, you solve mixture problems again, but they should be easier now.
Here are videos of functions, domain and range, Systems of equations with 2 variables, and mixture problems
When you are finished, turn the homework in here at the bottom of the page. Due dates are on the schedule.
