HELP ME!! Move the terms to their corresponding categories. Either Domain or Range.
ExtremeBDS [4]

Step-by-step explanation and answer:

To understand this problem, you must first understand the definition of domain and range. Domain is all possible x values (possible input), and range is all possible y values (possible output). Based on this, we can now sort the terms as the following:

Domain

  • Independent variable
  • Input value
  • X-value

Range

  • Dependent variable
  • Y-value
  • Output value

Hope this helps!!
