Lesson 6.2 Domain and Range

Lesson 6.2 video link here. (Video under development)

Thermometers are great tools for measuring temperature. As with many tools, you must select an appropriate thermometer for a particular job. For example, the thermometer you would use to measure the temperature outside is probably a different thermometer from the one you would use for cooking because the required temperature ranges differ. Similarly, not all relations involve the same values. The domain and range of a relation define the values utilized by a specific relation.


In Lesson 6.2, you will learn about

  • determining the domain and range of relations with different representations

  • expressing the domain and range in various ways

  • the difference between independent and dependent variables

  • continuous and discrete sets of data
