Step 1:

The function is one to one.

Find the inverse function, by interchanging the elements in the domain with the elements in the range.

For example the function receives  Mt wailaleale, hawaii as input and 460.00 as output, so the inverse function receives 460.00 as

input and Mt Wallaleale, Hawaii as output.

Step 2:

Domain set of inverse function is range of the function

Domain of inverse function is

Range set of inverse function is domain of the function.

Range set of inverse function 

{ Mt Waialeale, Hawaii, Monorovia,Liberia, Pago pago, American samoa, moulmein Burma, Lea ,papua New Guinea}
