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

I need the following info:

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.

Heart disease

Plot The data for each disease as points in a rectangular coordinate system.
Using a smooth line, connect your data points for each disease graph.
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:

1-Can the graphs that were 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?
