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?
