In the real world, functions are mathematical representations of input-output situations.

A vending machine is one such example. The input is the money combined with the

selected button. The output is the product.

Here is another example: The formula for converting a temperature from Fahrenheit to

Celsius is a function expressed as:

C = (5/9)*(F - 32), where F is the Fahrenheit temperature and C is the Celsius temperature.

If it is 77 degrees Fahrenheit in Phoenix Arizona, then what is the equivalent temperature

on the Celsius thermometer?

Our input is 77.

C = (5/9)*(77 - 32)

C = (5/9)*(45)

C = 25

The equivalent temperature is 25 degrees Celsius.
