The shape of the graph of an inverse relationship?

Answer 1

If two variables are inversely related, then a graph showing their relationship should be shaped like a hyperbola. A hyperbola will start out really high, drop a lot in a short distance, then drop less and less as the graph goes further to the right. It looks similar to an exponential decay function, but less extreme.

Here is an example of what one could look like:

(In most practical applications, only the right side of the graph would be shown.)
