# Functions and Graphs : Heart Disease, Cancer and AIDS - Trends and Real World Implications

You have been invited to present statistical information at a conference.

To prepare, you must perform the following tasks:

1. Search the Internet and the Cybrary to find the number of deaths in the United States due to each of the following medical conditions in each of these years; 1985, 1990, 1995, and 2002.:

o heart disease

o cancer

o AIDS

2. Plot your data for each disease as points in a rectangular coordinate system.

3. Using a smooth line, connect your data points for each disease graph.

4. Using each curve, make a reasonable prediction as to the number of deaths we might expect in 2005 due to each of these medical conditions.

Follow-up questions:

Please include responses to these questions with your submission.

1. Can the graphs that you constructed be classified as functions? Explain.

2. Why is it reasonable that negative numbers are excluded from both the domain and the range of each of the disease graphs? What would the real-world implications be if these numbers were actually part of the domain and/or range?
