# Relations vs Functions and Celsius-Fahrenheit Temperature Conversion

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

There is a formula that converts temperature in degrees Celsius to temperature in degrees Fahrenheit. If we use the following data points:

Fahrenheit Celsius

Freezing point of water 32 0

Boiling point of water 212 100

Whas is the linear equation that expresses temperature in degrees Fahrenheit as a function of temperature in degrees Celsius?

What is the linear equation that expresses temperature in degrees Celsius as a function of temperature in degrees Fahrenheit.

How do the graphs of these two functions differ?
