In a function, what does the range refer to?

The range of a function refers to all output variables, which are typically represented by y values. In the context of a function, the output is determined based on the corresponding input values from the domain. When you consider the relationship defined by the function, it maps each input to a specific output, and the range encompasses all of these outputs.

Understanding the range is crucial for interpreting the behavior of the function, as it reflects the values that the function can produce. For example, if you have a function that describes the height of a plant over time, the range would include all possible heights the plant can attain during that time period. This concept is fundamental in mathematics, as it helps in analyzing functions, evaluating them at specific points, and understanding their overall behavior within the given context.
