Functions and reversal of variables

Reference no: EM13123650

Where in the real world might be a situation arise where it would be preferable for data to form a relation but not a function? Please explain it to me in detail

If the varibles in an equation were reversed, what would happen to the graph of the equation? Here's an example of what I'm asking: how would the graph of y=x^2 relate to the graph x = y^2? When might this reversal of variables be useful in the real world?

Any and all help you can give will be greatly appreciated.
