I graduated high school in 1990 and we did not have someo f this and it has been soooooooo long ago. Can someone help me please??? Here are the questions...

In the real world, what might be a situation where it is preferable for the data to form a relation but not a function?

If the variables in an equation were reversed, what would happen to the graph of the equation? For example, how would the graph of y = x² relate to the graph of x = y²? When might such a reversal of variables be useful in the real world?

You have been invited to present statistical information at a conference. To prepare, you must perform the following tasks:

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.:
heart disease
cancer
AIDS
Plot your 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.
