Create graphs of functions

[Kaichie]

*** I NEED SOME HELP IN THIS****
As the financial manager of ABC computers, you are ready to make some
decisions.
You are trying to see where revenues are going—is the company ready to
expand, and if so, when? There is a lot of data that you have, but columns of
numbers are not as easy to understand as a graph.

You plot revenue as a function of time. You do not want to just know what
has happened in the past, you want to create a model that will help you
predict what will happen to revenues in the future. You can do this if you
can fit the data to some function, such as an exponential, quadratic,
rational, polynomial, or log plot.

To increase your understanding of these, choose one equation of each type:
linear, quadratic, polynomial, rational, exponential, and log. Plot each
equation on the same graph. Discuss and compare the appearance of each graph.
Describe the plot’s shape, the effect of any constants, and behavior for very
large or very small x or y.
